Flinders Island Isolated Power System (IPS) Connect 2016 T MAHMOUD Western Powerjames hamilton
The energy industry is rapidly evolving to take advantage of renewable resources and Western Power is embracing new technologies that will improve service and reliability to our customers. New and improving technologies such as solar, wind, wave and most importantly batteries are changing the way we think about the delivery and storage of electricity. One of these developments is the microgrid, which is essentially a small scale power grid that can operate independently (in ‘island mode’) or connect with the main electrical grid – think of a small suburb, or estate, that shares electricity and the cost of the infrastructure. A microgrid needs to control the flow of electricity of low or medium voltage, but does not need connection to a centralised generation or transmission network. Western Power has trialled the world’s first microgrid project that combines wave energy, solar (photovoltaic) energy, a desalination plant, and energy storage that connects to our large electricity network.

Community microgrids can provide cleaner, more reliable and affordable energy while improving resilience. They distribute clean local energy sources like solar across an entire substation area serving thousands of customers. This reduces costs, increases clean energy use, and ensures critical services receive power during disasters. Local governments can explore microgrids for facilities like hospitals, schools and emergency shelters to gain economic, environmental and security benefits for their communities.

Reactive Power Sharing Droop Control Strategy for DG Units in an Islanded Mic...IJMTST Journal
The proposed method mainly includes two important operations: error reduction operation and voltage
recovery operation. The sharing accuracy is improved by the sharing error reduction operation, which is
activated by the low-bandwidth synchronization signals. However, the error reduction operation will result in
a decrease in output voltage amplitude. Therefore, the voltage recovery operation is proposed to compensate
the decrease., due to increasing the demand of electricity as well as rapid depletion of fossil fuels, and the
government policies on reduction of greenhouse gas emissions , renewable energy technologies are more
attractive and various types of distributed generation sources, such as wind turbine generators and solar
photo voltaic panels are being connected to low-voltage distribution networks. Micro grid is an integrated
system that contain in s distributed generation sources, control systems, load management, energy storage
and communication infrastructure capability to work in both grid connected and island mode to optimize
energy usage. The paper presents a advanced control technique for a micro grid system which works
efficiently under a decentralized control system.
The document discusses issues with India's energy sector and argues that micro-grids are a promising solution. It notes problems like power outages over large areas caused by small transmission failures. Micro-grids could help by reducing transmission losses, integrating renewable energy sources in a reliable way, and providing last-mile connectivity to rural communities. However, the variability of renewable energy sources and unclear policies around areas like payment mechanisms have hindered the development of micro-grids in India. The document advocates studying both the individual characteristics of and collective approaches to renewable energy and micro-grids to help unlock their potential.
Greg Thomson - Community Microgrid - (17 oct 2014)annphancock
This document outlines a community microgrid initiative to increase local renewable energy generation while improving grid reliability. The objectives are to reach 25% or more of total energy consumed from local renewables, achieve cost-effective outcomes for communities, and accelerate deployments through partnerships. A showcase project in Hunters Point, San Francisco is described in collaboration with PG&E using an optimization approach to determine optimal locations and sizes of distributed energy resources (DER) like solar PV and energy storage. Baseline analysis found 30 MW of new PV could be added at optimal locations equaling 25% of annual energy without adverse grid impacts.

What the duck curve tells us about managing a green gridAndrew Gelston
This document discusses how the increasing use of renewable energy is changing net load patterns on the electric grid in California. It introduces the concept of the "duck curve" which depicts steep ramps in net load in the mornings and evenings as solar power comes online and offline. To reliably operate under these changing conditions, the grid requires flexible resources that can quickly adjust power production through ramping, storage and demand response. Issues like overgeneration and reduced frequency response may occur and will require mitigation strategies to maintain reliability as renewable penetration increases.

Evolving Lifecycles with High Resolution Site Characterization (HRSC) and 3-D...Joshua Orris
The incorporation of a 3DCSM and completion of HRSC provided a tool for enhanced, data-driven, decisions to support a change in remediation closure strategies. Currently, an approved pilot study has been obtained to shut-down the remediation systems (ISCO, P&T) and conduct a hydraulic study under non-pumping conditions. A separate micro-biological bench scale treatability study was competed that yielded positive results for an emerging innovative technology. As a result, a field pilot study has commenced with results expected in nine-twelve months. With the results of the hydraulic study, field pilot studies and an updated risk assessment leading site monitoring optimization cost lifecycle savings upwards of $15MM towards an alternatively evolved best available technology remediation closure strategy.

Recycling and Disposal on SWM Raymond Einyu pptxRayLetai1
Increasing urbanization, rural–urban migration, rising standards of living, and rapid development associated with population growth have resulted in increased solid waste generation by industrial, domestic and other activities in Nairobi City. It has been noted in other contexts too that increasing population, changing consumption patterns, economic development, changing income, urbanization and industrialization all contribute to the increased generation of waste.
With the increasing urban population in Kenya, which is estimated to be growing at a rate higher than that of the country’s general population, waste generation and management is already a major challenge. The industrialization and urbanization process in the country, dominated by one major city – Nairobi, which has around four times the population of the next largest urban centre (Mombasa) – has witnessed an exponential increase in the generation of solid waste. It is projected that by 2030, about 50 per cent of the Kenyan population will be urban.
Aim:
A healthy, safe, secure and sustainable solid waste management system fit for a world – class city.
Improve and protect the public health of Nairobi residents and visitors.
Ecological health, diversity and productivity and maximize resource recovery through the participatory approach.
Goals:
Build awareness and capacity for source separation as essential components of sustainable waste management.
Build new environmentally sound infrastructure and systems for safe disposal of residual waste and replacing current dumpsites which should be commissioned.
Current solid waste management situation:
The status.
Solid waste generation rate is at 2240 tones / day
collection efficiently is at about 50%.
Actors i.e. city authorities, CBO’s , private firms and self-disposal
Current SWM Situation in Nairobi City:
Solid waste generation – collection – dumping
Good Practices:
• Separation – recycling – marketing.
• Open dumpsite dandora dump site through public education on source separation of waste, of which the situation can be reversed.
• Nairobi is one of the C40 cities in this respect , various actors in the solid waste management space have adopted a variety of technologies to reduce short lived climate pollutants including source separation , recycling , marketing of the recycled products.
• Through the network, it should expect to benefit from expertise of the different actors in the network in terms of applicable technologies and practices in reducing the short-lived climate pollutants.
Good practices:
Despite the dismal collection of solid waste in Nairobi city, there are practices and activities of informal actors (CBOs, CBO-SACCOs and yard shop operators) and other formal industrial actors on solid waste collection, recycling and waste reduction.
Practices and activities of these actor groups are viewed as innovations with the potential to change the way solid waste is handled.
CHALLENGES:
• Resource Allocation.
Optimizing Post Remediation Groundwater Performance with Enhanced Microbiolog...Joshua Orris
Results of geophysics and pneumatic injection pilot tests during 2003 – 2007 yielded significant positive results for injection delivery design and contaminant mass treatment, resulting in permanent shut-down of an existing groundwater Pump & Treat system.
Accessible source areas were subsequently removed (2011) by soil excavation and treated with the placement of Emulsified Vegetable Oil EVO and zero-valent iron ZVI to accelerate treatment of impacted groundwater in overburden and weathered fractured bedrock. Post pilot test and post remediation groundwater monitoring has included analyses of CVOCs, organic fatty acids, dissolved gases and QuantArray® -Chlor to quantify key microorganisms (e.g., Dehalococcoides, Dehalobacter, etc.) and functional genes (e.g., vinyl chloride reductase, methane monooxygenase, etc.) to assess potential for reductive dechlorination and aerobic cometabolism of CVOCs.
In 2022, the first commercial application of MetaArray™ was performed at the site. MetaArray™ utilizes statistical analysis, such as principal component analysis and multivariate analysis to provide evidence that reductive dechlorination is active or even that it is slowing. This creates actionable data allowing users to save money by making important site management decisions earlier.
The results of the MetaArray™ analysis’ support vector machine (SVM) identified groundwater monitoring wells with a 80% confidence that were characterized as either Limited for Reductive Decholorination or had a High Reductive Reduction Dechlorination potential. The results of MetaArray™ will be used to further optimize the site’s post remediation monitoring program for monitored natural attenuation.
Kinetic studies on malachite green dye adsorption from aqueous solutions by A...Open Access Research Paper
Water polluted by dyestuffs compounds is a global threat to health and the environment; accordingly, we prepared a green novel sorbent chemical and Physical system from an algae, chitosan and chitosan nanoparticle and impregnated with algae with chitosan nanocomposite for the sorption of Malachite green dye from water. The algae with chitosan nanocomposite by a simple method and used as a recyclable and effective adsorbent for the removal of malachite green dye from aqueous solutions. Algae, chitosan, chitosan nanoparticle and algae with chitosan nanocomposite were characterized using different physicochemical methods. The functional groups and chemical compounds found in algae, chitosan, chitosan algae, chitosan nanoparticle, and chitosan nanoparticle with algae were identified using FTIR, SEM, and TGADTA/DTG techniques. The optimal adsorption conditions, different dosages, pH and Temperature the amount of algae with chitosan nanocomposite were determined. At optimized conditions and the batch equilibrium studies more than 99% of the dye was removed. The adsorption process data matched well kinetics showed that the reaction order for dye varied with pseudo-first order and pseudo-second order. Furthermore, the maximum adsorption capacity of the algae with chitosan nanocomposite toward malachite green dye reached as high as 15.5mg/g, respectively. Finally, multiple times reusing of algae with chitosan nanocomposite and removing dye from a real wastewater has made it a promising and attractive option for further practical applications.
Microbial characterisation and identification, and potability of River Kuywa ...Open Access Research Paper
Water contamination is one of the major causes of water borne diseases worldwide. In Kenya, approximately 43% of people lack access to potable water due to human contamination. River Kuywa water is currently experiencing contamination due to human activities. Its water is widely used for domestic, agricultural, industrial and recreational purposes. This study aimed at characterizing bacteria and fungi in river Kuywa water. Water samples were randomly collected from four sites of the river: site A (Matisi), site B (Ngwelo), site C (Nzoia water pump) and site D (Chalicha), during the dry season (January-March 2018) and wet season (April-July 2018) and were transported to Maseno University Microbiology and plant pathology laboratory for analysis. The characterization and identification of bacteria and fungi were carried out using standard microbiological techniques. Nine bacterial genera and three fungi were identified from Kuywa river water. Clostridium spp., Staphylococcus spp., Enterobacter spp., Streptococcus spp., E. coli, Klebsiella spp., Shigella spp., Proteus spp. and Salmonella spp. Fungi were Fusarium oxysporum, Aspergillus flavus complex and Penicillium species. Wet season recorded highest bacterial and fungal counts (6.61-7.66 and 3.83-6.75cfu/ml) respectively. The results indicated that the river Kuywa water is polluted and therefore unsafe for human consumption before treatment. It is therefore recommended that the communities to ensure that they boil water especially for drinking.
Improving the viability of probiotics by encapsulation methods for developmen...Open Access Research Paper
The popularity of functional foods among scientists and common people has been increasing day by day. Awareness and modernization make the consumer think better regarding food and nutrition. Now a day’s individual knows very well about the relation between food consumption and disease prevalence. Humans have a diversity of microbes in the gut that together form the gut microflora. Probiotics are the health-promoting live microbial cells improve host health through gut and brain connection and fighting against harmful bacteria. Bifidobacterium and Lactobacillus are the two bacterial genera which are considered to be probiotic. These good bacteria are facing challenges of viability. There are so many factors such as sensitivity to heat, pH, acidity, osmotic effect, mechanical shear, chemical components, freezing and storage time as well which affects the viability of probiotics in the dairy food matrix as well as in the gut. Multiple efforts have been done in the past and ongoing in present for these beneficial microbial population stability until their destination in the gut. One of a useful technique known as microencapsulation makes the probiotic effective in the diversified conditions and maintain these microbe’s community to the optimum level for achieving targeted benefits. Dairy products are found to be an ideal vehicle for probiotic incorporation. It has been seen that the encapsulated microbial cells show higher viability than the free cells in different processing and storage conditions as well as against bile salts in the gut. They make the food functional when incorporated, without affecting the product sensory characteristics.

or more substations – ultimately including a transmission-
distribution substation that sets the stage for Distribution
System Operator (DSO) performance.
• Ability to utilize existing distribution grid infrastructure to serve
the Community Microgrid during broader grid outages
• High penetrations of local renewables and other distributed
energy resources (DER) such as energy storage and demand
response.
• Staged capability for indefinite renewables-driven backup
power for critical community facilities across the grid area –
achieved by 25% local renewables mix.
• A solution that can be readily extended throughout a utility
service territory – and replicated into any utility service territory
around the world.

Value of Resilience (VOR) depends on tier of load
• Everyone understands there is significant value to resilience provided by indefinite renewables-
driven backup power
• But, nobody has yet to quantify this value of unparalleled resilience.
• Hence, there is an economic gap for innovative Community Microgrid projects while learning is still is
the early stages.
• The Clean Coalition aims to establish standardized Value of Resilience (VOR) for critical, priority,
and discretionary loads that will help everyone understand that premiums are appropriate for
indefinite renewables-driven backup power of critical loads and almost constant backup power
to priority loads, which yields a configuration that delivers backup power to all loads a lot of
the time
• The Clean Coalition’s VOR approach will establish
standardized values for resilience of three tiers of
loads:
• Tier 1 are mission-critical and life-sustaining loads,
crucial to keep operational at all times, including during grid outages.
Tier 1 loads usually
represent about 10% of the total load.
• Tier 2 are priority loads that should be maintained as long as long as
doing so does not threaten the ability to maintain Tier 1 loads. Tier 2
loads are usually about 15% of the total load.
• Tier 3 are discretionary loads make up the remaining loads, usually
about 75% of the total load, and are maintained when doing so does
not threaten the ability to maintain Tier 1 & 2 loads.

Goleta Load Pocket (GLP)
The GLP is the perfect opportunity for a comprehensive Community Microgrid
• GLP spans 70 miles of California coastline, from Point Conception to Lake Casitas,
encompassing the cities of Goleta, Santa Barbara (including Montecito), and Carpinteria.
• GLP is highly transmission-vulnerable and disaster-prone (fire, landslide, earthquake).
• 200 megawatts (MW) of solar and 400 megawatt-hours (MWh) of energy storage will
provide 100% protection to GLP against a complete transmission outage (“N-2 event”).
• 200 MW of solar is equivalent to about 5 times the amount of solar currently deployed in the GLP and
represents about 25% of the energy mix.
• Multi-GWs of solar siting opportunity exists on commercial-scale built-environments like parking lots,
parking structures, and rooftops; and 200 MW represents about 7% of the technical siting potential.
• Other resources like energy efficiency, demand response, and offshore wind can significantly reduce
solar+storage requirements.
