TL;DR: In this paper , the authors present solar water pumping technologies, performance analyses, economic and environmental implications, as well as breakthroughs in PV materials, and demonstrate how various parameters affect its performance.
Abstract: Since the lack of power has an impact on community water supply pumping requirements, harnessing solar energy in water pumping seems to be a possible alternative to traditional electrical pumping systems. The solar pump system has become widely used in the agriculture, industry, and domestic markets in recent years as a result of continual improvement. Photovoltaic (PV) technology turns solar energy into electricity, which is used to power a Dc and Ac motor-based pump. This article presents solar water pumping technologies, performance analyses, economic and environmental implications, as well as breakthroughs in PV materials. Simulation software aids in the design of the system and demonstrates how various parameters affect its performance. For domestic as well as industrial appliances and water supply in rural, urban, and distant areas, solar PV systems are more cost-effective than electricity or fuel systems. Solar water pumping systems have a 4-4 year investment payback period. By using this, the cost of the electricity bill, in the long run, is reduced. The generated electricity can also be given to the grid to save on the generation of electricity. The output results are validated through Simulink/MATLAB.

TL;DR: In this paper , the authors proposed a framework for the advancement of the change of sun-based energy into power by appropriately arranging the board as per the place of the sun as well as wind turbine.
Abstract: Today energy is the fundamental motivation for financial improvement. Yet, because of the gradual pace of ecological concern, sustainable power gives a huge interest. This elective power source is persistently accomplishing more noteworthy fame because of persistent decrease in fossil powers. It is the energy comes from sun, wind, downpour and so on Among the non-customary, sustainable power sources, sun powered energy manages the cost of incredible potential for change into electric power and wind turbine based power as well. Expanding power yield from a sun based framework is alluring to increment productivity. To amplify power yield, requirements to keep the boards adjusted with the sun. This paper manages the power age utilizing sun based power and wind power. The proposed framework guarantees the advancement of the change of sun-based energy into power by appropriately arranging the board as per the place of the sun as well as wind turbine.
TL;DR: In this article , a simulation of 3.3 kWp and 2.2 kWp residential solar PV systems with and without subsidy scenarios were considered for simulation using RETscreen software, and they found that high installation costs, subsidized utility grid supply to low energy consumer and financing rates are major barriers to grid parity.
Abstract: Rooftop solar photovoltaic(PV) installation in India have increased in lastdecade because of the flat 40 percent subsidy extended for rooftop solarPV systems (3 kWp and below) by the Indian government under the solarrooftop scheme. From the residential building owner’s perspective, solar PVis competitive when it can produce electricity at a cost less than or equalgrid electricity price, a condition referred as “grid parity”. For assessing gridparity of 3 kWp and 2 kWp residential solar PV system, 15 states capitaland 19 major cities were considered for the RET screen simulation by usingsolar isolation, utility grid tariff, system cost and other economic parameters.3 kWp and 2 kWp rooftop solar PV with and without subsidy scenarioswere considered for simulation using RETscreen software. We estimate thatwithout subsidy no state could achieve grid parity for 2kWp rooftop solarPV plant. However with 3 kWp rooftop solar PV plant only 5 states couldachieve grid parity without subsidy and with government subsidy number ofstates increased to 7, yet wide spread parity for residential rooftop solar PV isstill not achieved. We find that high installation costs, subsidized utility grid supply to low energy consumer and financing rates are major barriers to gridparity
TL;DR: In this article , a high-level business case analysis to assess renewable electricity options considering their impact on the green hydrogen levelized cost of hydrogen (LCOH) in an off-grid configuration is presented.
Abstract: Green hydrogen development is still at a niche stage and faces several technical & commercial barriers. Among them is the high LCOH (Levelized Cost of Hydrogen) of green hydrogen, predominantly due to the cost of renewable electricity. In recent years, several research studies have focused on finding the most cost-effective renewable electricity option to feed electrolyzers for producing green hydrogen. However, their findings suggest that renewable electricity costs vary widely between solar, onshore wind, and offshore wind technologies based on the meteorological conditions of the location. With a focus on the United Kingdom (UK), this paper does a high-level business case analysis to assess renewable electricity options considering their impact on the green hydrogen LCOH in off-grid configuration. The paper uses the cost and capacity factors of renewable electricity generated from solar, onshore wind, and offshore wind in the UK. The paper discusses how offshore wind electricity in an off-grid configuration could be the most effective in bringing down the green hydrogen LCOH and reducing offshore wind curtailments in the UK.

TL;DR: In this paper , a source-grid-load-storage power system coordinated expansion planning model that considers demand response services is proposed, which can effectively guarantee the safety of power system operation and improve the absorption capacity of wind and light energy.
Abstract: With the increase of wind and solar power plants, the uncertainty of their output also brings challenges to the power system. These factors should also be considered in long-term planning of the power system. Therefore, a source-grid-load-storage power system coordinated expansion planning model that considers demand response services is proposed in this paper. In this way, the ability to absorb large-scale renewable energy such as light and wind in the power system is improved. First, the power system operation model is proposed in this paper; secondly, the demand response services and electricity storage facility are modeled in detail; then demand response and electricity storage facility resources are used to alleviate the intermittent output of wind and solar power plants on the power side. A load-side demand response service planning model is proposed, and a source-network-load coordination planning model is proposed. Finally, the rationality of the model is verified through the analysis of simulation examples, and the advantages of the coordinated planning of source-grid-load-storage power system are proved. In addition, it can effectively guarantee the safety of power system operation and improve the absorption capacity of wind and light energy.
