The increasing penetration of Renewable Energy Sources (RESs) in the energy mix is determining an energy scenario characterized by decentralized power production. Between RESs power generation technologies, solar PhotoVoltaic (PV) systems constitute a very promising option, but their production is not programmable due to the intermittent nature of solar energy. The coupling between a PV facility and a Battery Energy Storage System (BESS) allows to achieve a greater flexibility in power generation. However, the design phase of a PV+BESS hybrid plant is challenging due to the large number of possible configurations. The present paper proposes a preliminary procedure aimed at predicting a family of batteries which is suitable to be coupled with a given PV plant configuration. The proposed procedure is applied to new hypothetical plants built to fulfill the energy requirements of a commercial and an industrial load. The energy produced by the PV system is estimated on the basis of a performance analysis carried out on similar real plants. The battery operations are established through two decision-tree-like structures regulating charge and discharge respectively. Finally, an unsupervised clustering is applied to all the possible PV+BESS configurations in order to identify the family of feasible solutions.

The potential crisis of energy and the deterioration of ecological environment make the world's cumbersomedevelopment of renewable energy including new energy, including solar energy. Traditional energy in the coal, oil andnatural gas are evolved from ancient fossils, it is collectively referred to as fossil fuels. As the world's energy needscontinue to increase, fossil fuels will also be depleted, it is necessary to fi nd a new energy to replace the traditionalenergy. Solar energy is a clean renewable energy with mineral energy incomparable superiority. Modern society shouldbe a conservation-oriented society, and social life should also be a life-saving energy. At the same time, Premier WenJiabao also proposed on June 30, 2005 and stressed the need to speed up the construction of a conservation-orientedsociety. And solar energy as an inexhaustible new environmentally friendly energy has become the world's energyresearch work in the world an important issue. Is the world in the economic situation to take a simpler, economical,environmentally friendly and reliable building heating and heating energy-saving measures. This paper summarizes thecurrent global energy status, indicating the importance of solar power and prospects. Details of the various solar powergeneration methods and their advantages, and made a comparison of this power generation parameters. At the sametime pointed out that the diffi culties faced by solar power and solutions, as well as China's solar power of the favorableconditions and diffi culties. The future of China's solar energy made a prospect.

The penetration level of a PV system is often limited due to the violation of voltage variation introduced by the large intermittent power generation. This paper discusses the use of an active power curtailment strategy to reduce PV power injection during peak solar irradiation to prevent voltage violation so that the PV penetration level of a distribution feeder can be increased to fully utilize solar energy. When using the proposed voltage control scheme for limiting PV power injection into the study distribution feeder during high solar irradiation periods, the total power generation and total energy delivered by the PV system over a 1-year period are determined according to the annual duration of solar irradiation. With the proposed voltage control to perform the partial generation rejection of PV systems, the optimal installation capacity of PV systems can be determined by maximizing the net present value of the system so that better cost effectiveness of the PV project and better utilization of solar energy can be obtained.

In order to build an environment-friendly society and realize the coordinated allocationand effective utilization of resources and finally achieve China’s energy supply security, it isimperative to vigorously develop new energy sources. This study establishes a four-level newenergy power generation (NEPG) development index system from multiple dimensions. Takingthe installed capacity and generating capacity of China’s NEPG in 2016 and 2017 as samples, weused the improved entropy method, to analyze the development of different types of NEPG among31 provinces from three aspects: absolute value, relative value, and incremental value. Finally, wecomprehensively evaluated the NEPG development in each province. The empirical analysisshows that the spatial distribution of NEPG development in China is uneven, the growth rate isdifferent, the development gap is obvious, and the development efficiency is quite different.

In this paper, the performance of a new Z-source inverter (ZSI)-based single-stage power conditioning system (PCS) is analyzed for a standalone photovoltaic (PV) power generation system. The proposed ZSI-based PCS includes two main parts: one is the input from PV units and the other is the ZSI. In this work, a new topology, termed the switched inductor-assisted strong boost ZSI (SL-SBZSI), is introduced for improving the performance of the PCS. The proposed topology shows high boosting capability during the voltage sag in PV units due to variations in solar irradiation and temperature. Another key advantage is the reduced capacitor voltage stress and semiconductor switch voltage stress of the inverter bridge, which ultimately minimizes the size and cost of the single-stage PCS. The proposed ZSI topology falls under the doubly grounded category of inverter by sharing the common ground between the input and output. This is an additional feature that can minimize the leakage current of PV units at the ac output end. The operational principles, detailed mathematical modeling, and characteristics of the proposed SL-SBZSI for a standalone photovoltaic (PV) power generation system is presented in this paper for analyzing performance. The simulation results, which are performed in MATLAB/Simulink, demonstrate the improved performance of the proposed SL-SBZSI for the standalone PV system. The performance of the proposed topology is also evaluated through an experimental validation on a laboratory-based PV system.
