The results show that the configuration of energy storage for household PV can significantly reduce PV grid-connected power, improve the local consumption of PV power, promote the safe and stable operation of the power grid, reduce carbon emissions, and achieve appreciable economic benefits.
In addition, various inverter topologies i.e. power de-coupling, single stage inverter, multiple stage inverter, transformer and transformerless inverters, multilevel inverters, and soft switching inverters are investigated. It is also discussed that the DC-link capacitor of the inverter is a limiting factor.
In general, on the basis of transformer, the grid-connected PV inverter topologies are categorized into two groups, i.e., those with transformer and the ones which are transformerless. Line-frequency transformers are used in the inverters for galvanic isolation of between the PV panel and the utility grid.
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.
The operation mode is that the PV is self-generation and self-consumption, and the surplus PV power is connected to the grid. According to the optimized configuration results of energy storage under the grid-connected mode, the detailed operation of the household PV storage system in each season in Scenario 4 is shown in Fig. 21, Fig. 22, Fig. 23.
The leakage path is interrupted by the galvanic isolation provided by the transformer, however additional losses in transformer reduces the efficiency. Several, transformerless inverter topologies are used to minimize the effect of HF harmonics on the leakage currents .
