Design of Hybrid Solar-Wind Power System for a Coaster Area in Lagos State, S...paperpublications3
Abstract: Akodo community in Ibeju Lekki local government area of Lagos State is a rural area without access to grid electricity. Extension of the grid to the community is difficult and uneconomical; hence a hybrid energy system stands as a solution for electrification in Akodo.
In this project, the HOMER (Hybrid Optimization Model for Electric Renewables) software was used to simulate a Solar and Wind hybrid system. In terms of energy delivery, the design was adequate for the 89kW load of the community. The important variables in the simulation are the level of availability of resources and the slope of the PV modules. The slope of the modules at 12o and 15o gave different levelised costs of energy (LCOE) of N27.521/kWh for the 12o PV slope and N28.846/kWh for the 15o PV slope. The PV slope at 12o is more desirable and more economical than that at 15o. The hybrid system is proposed for a project lifetime of 25 years.

The slides for a presentation on Energy harvesting and the state off the art designs currently taking advantage of the energy around us.
Energy harvesting (also known as power harvesting or energy scavenging) is the process by which energy is derived from external sources (e.g.solar power, thermal energy, wind energy, salinity gradients, and kinetic energy), captured, and stored for small, wireless autonomous devices, like those used in wearable electronics and wireless sensor networks.

Paul Ahern - Piezoelectric Energy Harvesting ReviewPaul Ahern
Mechanical energy is among the most plentiful and consistent energy sources in our day-to-day lives, which is available to us regardless of the whims of the weather or the cycles of day and night. Piezoelectric Energy Harvesters (PEH’s) are compact devices which allow the scavenging of low grade energy from ambient sources such as human and environmental vibrations, with the aim of using this energy to power autonomous electronic devices. Many decades of research and development in the field has led to commercially available devices based on piezoelectric materials which can be used to harvest milliwatts of energy from mechanical sources such as vibration, stress or strain.
These slides use concepts from my (Jeff Funk) course entitled analyzing hi-tech opportunities to show how energy harvesters are becoming more economically feasible for the Internet of Things (IoT). Small amounts of energy can be harvested from vibrations, temperature differences, and radio frequencies using various types of electronic devices such as piezoelectric, MEMS, thermo-electric power generators, and other devices. As improvements in them occur and as the energy requirements of accelerometers, pressure sensors, gas detectors, bio-sensors, and readout circuits fall from microwatts to hundreds of nano-watts, energy harvesters become cheaper and better than are batteries. Improvements in energy harvesting are occurring in the form of higher power per area or higher power per temperature difference and improvements of about five times are expected to occur in the next 5 to 10 years. The market for energy harvesters is expected to reach $2.5 Billion by 2024. In addition to their impact on buildings and the other usual applications for IoT, they will also impact on agriculture, aircraft, and medical implants.
OPTIMAL PLACEMENT OF DISTRIBUTED GENERATION FOR LOSS REDUCTION IN DISTRIBUTIO...ijiert bestjournal
Due to the increasing interest on renewable sources in recent times,the studies on integration of distributed generation to the power grid have rapid ly increased. Distributed generations (DGs) play an important role in distribution networks. Am ong many of their merits,loss reduction and voltage profile improvement can be the salient spec ifications of Distributed generations (DG). Non-optimal locations and non-optimal sizes of Dist ributed generations (DG) units may lead to increase losses,together with bad effect on voltag e profile. Proper location of Distributed generations (DGs) in power systems is important for obtaining their maximum potential benefits. Distributed generation (DG) units reduce electric p ower losses and hence improve reliability and voltage profile. Determination of appropriate size and location of Distributed generation (DG) is important to maximize overall system efficiency. In this project,Newton raphson method optimization technique has been presented to determ ine the appropriate size and proper allocation of Distributed generation (DG) in a dist ribution network.So,this project focus towards,at determining optimal DG allocation and s izing as well as analyzing the impact of Distributed generation (DG) in an electric power sy stem in terms of voltage profile improvement and line loss reduction
In modern days, the use of energy consumption increasing very rapidly. Fossil fuels are finite and environmentally costly. Sustainable, environmentally benign energy can be derived from nuclear fission or captured from ambient sources. Large-scale ambient energy (eg. solar, wind and tide), is widely available and large-scale technologies are being developed to efficiently capture it. At the other end of the scale, there are small amounts of ‘wasted’ energy that could be useful if captured. Recovering even a fraction of this energy would have a significant economic and environmental impact. This is where energy harvesting (EH) comes in.
Testing and Development of Power Generation from Exhaust Gas of Motor Bikeijtsrd
This project presents the investigation of power generation using the mixture of heat and thermo electric generators. A majority of thermal energy in two wheeler silencer is dissipated as waste heat to the environment. This waste heat may be utilized further for power generation. The related problems of worldwide warming and dwindling fuel supplies has led to improving the efficiency of any process being a priority. One method to boost the efficiency is to develop methods to utilize waste heat that is usually wasted. Two promising technologies that were found to be useful for this purpose were thermoelectric generators and warmth pipes. Subsequently, this venture included creation a seat type, verification of idea model of intensity creation by thermoelectric generators utilizing heat pipes and reenacted sight seeing. In recent years, heating and also the limitations in use of energy resources increase environmental problems with emissions. Additionally In industry, the greater part of the costs are a direct result of vitality both electrical and heat , work and materials. Yet, out of them vitality would identify with the sensibility of the expense or potential cost assets and so vitality the board will help in cost decrease. The possibilities of thermoelectric systems' contribution to "green" technologies, specifically for waste heat recovery from two wheeler silencer exhausting flue gases. It results into broad research on green advances creating power. As waste heat recovering techniques, like thermoelectric generator TEG is developed. Its implementation in automobile vehicles is administered in some ways. Tanveer Hussain | Kishore. N.
