“…Under the premise of the same battery capacity, when the photovoltaic panel installation power is low, the self-sufficiency rate of residential load is much lower than that of industrial load and commercial load , which is caused by the load characteristic curve of residential load and sunshine time being opposite. When the installed power of photovoltaic panels is high, even under the premise of the same battery capacity, the self-sufficiency rate of residential load, commercial load and industrial load is not different, but the self-sufficiency rate of residential load is greater than the self-sufficiency rate of industrial load and commercial load, which is opposite to the distribution trend of small installed power of photovoltaic panels [21,22].…”

In this paper, make use of PVSOL software studied the generation performance and Economic benefits of PV system at various inclinations. And then analyzed residential load, industrial load and commercial load system performance and self-sufficiency under different battery capacity. The results show that for Shanghai area, when the inclination angle of PV panel is about 23o, the annual total power generation of PV system reaches the maximum. The self-sufficiency rate of PV systems with industrial load is higher than commercial load, and the self-sufficiency rate of PV systems with residential load is the lowest. The self-sufficiency rate of PV systems with batteries are higher than PV systems without batteries, and the increment of installation power can increase self-sufficiency rate of the PV system.

“…In terms of PV absorption, in [5], the time-shift characteristics of EES and the fast response of DC modulation are utilized to absorb grid-connected photovoltaics. In [6], the use of EES is proposed to solve the intermittent problem of solar energy resources and improve the photovoltaic absorption rate. However, the two scenarios did not effectively consider the impact of NEEV load integration on the distribution network.…”

In response to issues such as reduced voltage flexibility caused by the integration of a large number of high-proportion distributed photovoltaic (HPDP) and new energy electric vehicles (NEEV) into the distribution networks, this article proposes a method for evaluating the voltage flexibility (VF) of distributed PV distribution networks with high proportions and corresponding governance measures, which can effectively improve the VF of distribution networks and the absorption rate of photovoltaic (PV) systems. Firstly, we build an integrated system model for PV, electrochemical energy storage (EES), and distributed charging piles (DCP). Then, from a spatial perspective, a VF evaluation method for HPDP distribution networks is proposed. We analyze the impact of HPDP integration on the VF of each node in the distribution network and propose a governance measure that combines EES and DCP to enhance the VF of the distribution network. Finally, we take a typical 10 kV distribution network architecture in Jilin Province as an example for numerical analysis, so the effectiveness of the proposed method is verified.

“…However, the battery storage technology has been identified as a costly option [25]. For instance, Reference [26] evaluated the economic viability of a GCPV system with battery storage and concluded that the proposed system is not profitable without the financial support. The high cost issue may be a key hurdle in the adoption of the renewable energy based power systems.…”

The grid-connected photovoltaics (GCPV) systems are a sustainable alternative to the conventional non-renewable electricity systems. However, GCPV systems create the many issues such as grid overloading, demand and supply variations, and power quality issues. A key way to address such issues is the integration of the effective energy storage technologies in GCPV systems. There are many storage technologies which can be connected with GCPV systems. The integration of a proper storage technology into the GCPV systems may provide a best alternative. This paper evaluates the different storage technologies for GCPV systems using the analytic hierarchy process (AHP) approach. The goal of the AHP model was the selection of the best storage alternative for GCPV systems based on the multiple criteria. The criteria included the storage parameters as well as the parameters related to the compatibility with GCPV systems. The results exhibited that the pumped hydro storage is the best alternative if all the storage and compatibility parameters are equally desirable. However, if AHP model gives the highest preference to the criteria ''integration simplicity regarding renewable energy'' and ''geographic limitations'', the several other storage technologies achieve the higher rankings. Hence, the AHP model provides a greater flexibility to evaluate the different storage technologies for GCPV systems under different circumstances.INDEX TERMS Analytic hierarchy process (AHP), electrical power grid, environmental sustainability, power flow balancing, power system planning, power system reliability, renewable energy, solar energy, PV.
