This document summarizes a 3 kVA grid-supported residential solar energy system located in Pune, India. The system includes solar panels occupying 250 square feet that generate up to 3 kVA of power, 4 lead-acid batteries totalling 600 Ah of storage, and a power conditioning unit that interfaces the solar, batteries, and grid. Data from the system over sunny, partly cloudy and cloudy days shows how it charges and discharges the batteries and draws from the grid. Observations note the system could generate more power but batteries are too expensive, and more intelligent controls are needed to better optimize battery usage and minimize grid usage.
The document discusses the installation of a 5 kW on-grid solar power plant using a net-metering system and solar inverter. It describes the different types of solar systems based on the inverter used - on-grid, off-grid and hybrid. On-grid systems can operate without batteries or with batteries for backup. Off-grid systems include batteries for backup when the grid is down. Hybrid systems combine solar with other renewable sources like wind or generators. The document also examines the advantages of different inverter types for on-grid systems - micro, string and central, concluding that grid supportive solar PV provides economic and eco-friendly electricity production.
This document discusses PV-Wind hybrid systems which combine photovoltaic solar panels and wind turbines to generate electricity. Such hybrid systems are well-suited for locations where sunlight and wind availability vary seasonally. Key components include solar panels, a wind turbine, batteries, an inverter to convert DC to AC power, and instrumentation to monitor performance. Advantages are 24-hour power generation and reduced outage risks from multiple energy sources, while disadvantages include higher infrastructure costs and intermittent wind. Further research can improve performance and integration of renewable technologies.
Grid Tie Systems often prove to be a bit difficult to understand for the people enthusiastic to learn about Solar. We have tried to present it in an easy to understand form with differently colored arrows showing the current flow.

A microgrid is a small-scale power supply network that is designed to provide power for a small community. It enables local power generation for local loads. It comprises of various small power-generating sources that makes it highly flexible and efficient.
The document discusses the electric grid and grid-connected solar PV systems. It describes the electric grid as an interconnected network that balances supply and demand of electricity across its three main components: generation, transmission, and distribution. It then explains that grid-connected PV systems use solar panels to generate DC electricity, an inverter to convert it to AC electricity, and can both supply excess electricity to the grid and draw from the grid when solar power is insufficient, providing a reliable source of renewable energy with reduced costs compared to off-grid systems.
Rooftop solar systems are an off-grid solution for rural electrification that involve solar panels, charge controllers, storage batteries, and inverters. The solar panels convert sunlight to electricity that is stored in batteries. An inverter then converts the stored energy to AC power to run loads like AC units, TVs, refrigerators, and computers without needing a connection to the electric grid. Designing a rooftop solar system involves determining the daily load, selecting appropriately sized solar panels, batteries, and inverter based on the load and site conditions like sunlight hours and panel placement.

This document summarizes a research paper about a solar PV-based multistage grid-tie inverter. The paper proposes a multistage inverter topology to improve the waveform of line current from solar PV arrays connected to the electric grid. The topology eliminates the need for a separate DC-DC converter for maximum power point tracking (MPPT), thus improving efficiency and reducing costs compared to conventional designs. The paper describes the proposed two-stage converter topology, switching sequence, and experimental testing of a prototype to verify the MPPT scheme without a separate DC-DC converter stage.
This document discusses photovoltaic (PV) systems, which convert sunlight directly into electricity using solar cells. It describes two main types of PV systems: grid-tie systems, which are connected to the utility power grid and can supply power to a home while also sending excess power back to the grid; and off-grid systems, which operate independently without a grid connection and require batteries to store solar power for use when the sun isn't shining. The basic components of PV systems are described as solar modules, inverters to convert DC to AC power, charge controllers, and batteries for off-grid systems. Installation examples and diagrams of both grid-tie and off-grid systems are provided.
The document discusses two alternatives for a proposed 100kW solar photovoltaic rooftop power plant project in India. Alternative A involves a system with battery backup, while Alternative B is a grid-interactive system without battery storage. Both alternatives are analyzed in terms of their project tasks, timelines, costs including materials, labor and utilities, and projected returns. Alternative B is identified as the better option due to lower maintenance costs and avoiding issues with a battery bank. A SWOT analysis and critical path analysis are also provided to evaluate the project alternatives.
Micro-grids supply energy to rural areas using multiple distributed energy sources and manage supply and demand complexities. They include renewable sources like solar PV, biomass and waste heat recovery. Micro-grids have lower transmission losses than large-scale generation. They reduce grid upgrades needed by lowering transmission loads. Components include distributed generation sources, communication controls, and energy storage like batteries. Flow batteries are well-suited for bulk storage applications due to their longevity and lesser maintenance requirements. Lithium-ion batteries are applicable when precision and system dependence is high.

Bangalore | Jul-16 | MINI/MICRO GRID FOR RURAL AREASSmart Villages
This document discusses policies, frameworks, issues and challenges related to mini/micro grids for rural electrification in India. It provides an overview of the government's initiatives to expand electricity access such as strengthening the distribution network and deploying both grid-connected and off-grid renewable energy systems. Mini/micro grids are presented as an option to provide electricity access to all. Benefits, components, costs and examples of mini/micro grid projects are described. Key issues and challenges discussed include paying capacity, existing free power policies, lack of guidelines for grid integration and exit options. A draft framework to address these issues is being developed through stakeholder consultations.
Distributed generation takes advantage of small-scale power generation located near end users to provide electricity with benefits over traditional large-scale power plants. These include increased reliability as failures have localized impact, flexibility to adopt new technologies more easily, and reduced transmission losses. However, issues can include difficulty with load following due to variable renewable sources, potential voltage and stability problems integrating with the grid, and higher capital costs compared to large plants. Careful planning is needed to address power quality impacts on frequency and voltage from large amounts of distributed generation as well as connection challenges like bidirectional power flows, protection schemes, reactive power support, and power conditioning.
Small wind electric systems can provide homeowners with renewable energy and lower electricity bills. They generally consist of a rotor, generator, tower, and other balance of system components like batteries or connections to the electric grid. The size of the turbine's rotor determines how much power it can produce, with systems ranging from under 1 kW for battery charging up to 300 kW for institutional use. Taller towers capture higher wind speeds but also increase costs and risk damage in hurricanes. Successful small wind projects in India have shown that depending on wind resources, homeowners can reduce their electricity bills by 50-90% with these systems.

MicroGrid and Energy Storage System COMPLETE DETAILS NEW PPT Abin Baby
A microgrid is a localized grouping of electricity generation, energy storage, and loads that normally operates connected to a traditional centralized grid (macrogrid). This single point of common coupling with the macrogrid can be disconnected. The microgrid can then function autonomously. Generation and loads in a microgrid are usually interconnected at low voltage. From the point of view of the grid operator, a connected microgrid can be controlled as if it were one entity.
Microgrid generation resources can include fuel cells, wind, solar, or other energy sources. The multiple dispersed generation sources and ability to isolate the microgrid from a larger network would provide highly reliable electric power. Produced heat from generation sources such as micro turbines could be used for local process heating or space heating, allowing flexible trade off between the needs for heat and electric power.
This document discusses power system stability and microgrids. It defines power system stability and classifies it into several types including rotor angle stability, voltage stability, and frequency stability. It also discusses microgrids, their interconnection to main grids for availability and economic benefits, and methods for connecting microgrids using switchgear or static switches. In conclusion, it states that power system stability is important for normal operation and can be improved through devices like capacitors and FACTS controllers, and that microgrids satisfy local loads while reducing transmission losses through local renewable generation.
The document discusses smart grid technology, including its key features and components. A smart grid uses two-way digital communication to deliver power more efficiently by integrating renewable energy, automated demand response, and distributed generation.

Product Management is a complex and essential practice traversing multiple cross-functional areas within the company. While it is a well known practice in various well established product companies, most Product Management aspects are still adhoc within a startup, largely decided by the founders and the leadership teams, some based on gut, others based on fact-check with very few data points.
Startups are challenged to find the product-market fit early on and there is small room for errors. Hence, a thorough but low-touch Product Management toolkit and framework would be extremely essential for startups.
For IoT companies, it becomes much more complex with both hardware and software, where product management essentials have been very different. Another aspect is the customization you have to do for customers - where do you draw the line? How would you build the product and handle the customization, so that it can be provided easily to other customers with minimal efforts?

Its core banking applications run on the mainframe and Citizens was using legacy utilities to get the critical mainframe data to feed customer-facing channels, like call centers, web, and mobile. Ultimately, this led to higher operating costs (MIPS), delayed response times, and longer time to market.
Ever-changing customer expectations demand more modern digital experiences, and the bank needed to find a solution that could provide real-time data to its customer channels with low latency and operating costs. Join this session to learn how Citizens is leveraging Precisely to replicate mainframe data to its customer channels and deliver on their “modern digital bank” experiences.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Bram Verhoef, Head of Machine Learning at Axelera AI, presents the “How Axelera AI Uses Digital Compute-in-memory to Deliver Fast and Energy-efficient Computer Vision” tutorial at the May 2024 Embedded Vision Summit.
As artificial intelligence inference transitions from cloud environments to edge locations, computer vision applications achieve heightened responsiveness, reliability and privacy. This migration, however, introduces the challenge of operating within the stringent confines of resource constraints typical at the edge, including small form factors, low energy budgets and diminished memory and computational capacities. Axelera AI addresses these challenges through an innovative approach of performing digital computations within memory itself. This technique facilitates the realization of high-performance, energy-efficient and cost-effective computer vision capabilities at the thin and thick edge, extending the frontier of what is achievable with current technologies.
In this presentation, Verhoef unveils his company’s pioneering chip technology and demonstrates its capacity to deliver exceptional frames-per-second performance across a range of standard computer vision networks typical of applications in security, surveillance and the industrial sector. This shows that advanced computer vision can be accessible and efficient, even at the very edge of our technological ecosystem.

Summary
Consider 20KWp+ Hybrid.
Solar PV between 15-50KWp Hybrid grid .Small 2-10 KWp Wind/ Bio
Feed to grid 440V 3 phase to benefit for future net Metering
Use existing Genset backup rather then “overinvest” in Battery
Contracting Approach
Quality over cost as expensive if failures over 20-25 year cycle
Invertors and Installation (Wiring, enclosures) are hotspots.
IP6 Open Enclosures wind, water, hail, earthing, High DC Amperage flow …
Failure points and replacements costed in . Invertors etc
Need to arrange credible support for long term supply 15-20 years.
Consider some form of power purchase to keep engagement
We will buy Power at agreed rates for 10-12 years.
We will need to invest 30% of CAPEX ( 20-30L) for reasonable rates.
Alternative Energy projects are financed at 13%+ by Commercial banks
