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.
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.
The photovoltaic module in the household photovoltaic energy storage system was adopted from the Simscape Electrical Specialized Power Systems Renewable Energy Block Library in Matlab/SIMULINK. The photovoltaic module’s ambient temperature was set to 25 °C, and the illuminance was set to 1000 W/m 2.
The PV works in power limit mode, and the output current of the PV is reduced by controlling the boost converter. According to the photovoltaic I–V characteristic curve, the output voltage of the PV increases as a result and moves further away from the maximum power point.
Each photovoltaic module had an open circuit voltage of 37.5 V and a short-circuit current of 11.1 A. The maximum power point voltage and current were 30 V and 10 A, respectively. The number of PV series-connected modules per string was 10, and the number of parallel strings was 1.
The deviation between the inverter’s power-limiting value and the photovoltaic output power under the action of the proportional–integral (PI) controller can change the duty cycle of the boost converter, which can reduce the photovoltaic output power within 1 s. The principle of this method is simple, but the response speed is relatively slow.
