However, the configuration of energy storage for household PV can significantly improve the self-consumption of PV, mitigate the impact of distributed PV grid connection on the distribution network, ensure the safe, reliable and economic operation of the power system, and have good environmental and social benefits.
Residential loads and energy storage batteries consume PV power to the most extent. If there is still remaining PV power after the energy storage is fully charged, it is connected to the power grid. When the PV output is insufficient, the energy storage battery supplies power to the residential loads.
The household photovoltaic energy storage system is shown in Figure 1. The system consists of a topological structure layer, a control layer, and an energy management layer. Figure 1. Household photovoltaic and energy storage system.
By comparing the energy behavior of PV-battery and PV-only systems, it is found that the presence of the battery reduces peak power to and from the grid. For the system with actual sizes (residential SH), the energy sold to the grid is almost eliminated and there is a 60% reduction in the amount of electricity bought.
Daily experimental results show how the presence of energy storage reduces the midday feed-in of excess PV power and the evening peak demand, providing benefits to the distribution network in terms of reduced voltage swings and peak load.
The PV is composed of identical photovoltaic modules to provide active power for the system. The output voltage and current of the PV are sensitive to external factors (temperature, illuminance), and the output characteristic curve is nonlinear.
