Contact UsIt is a rational decision for users to plan their capacity and adjust their power consumption strategy to improve their revenue by installing PV–energy storage systems. PV power generation systems typically exhibit two operational modes: grid-connected and off-grid .
The PV-storage system is operated in constant power mode with the VSG inertia parameter of J = 2 × 10 4 kg m 2 and the power reference value of Pref = 150 kW. The simulation results of each power curve during steady-state operation and load step disturbance are shown in Fig. 7.
Secondly, to minimize the investment and annual operational and maintenance costs of the photovoltaic–energy storage system, an optimal capacity allocation model for photovoltaic and storage is established, which serves as the foundation for the two-layer operation optimization model.
In this paper, a selective input/output strategy is proposed for improving the life of photovoltaic energy storage (PV-storage) virtual synchronous generator (VSG) caused by random load interference, which can sharply reduce costs of storage device. The strategy consists of two operating modes and a power coordination control method for the VSGs.
According to the above parameters, the PV-storage system is operated in tracking PV mode, the initial PV output power is 150 kW, the PV power mutates to 200 kW at 20s, and the PV power mutates to 250 kW at 40s, and each power curve is shown in Fig. 9. Fig. 9. Power curve of PV step disturbance in tracking PV mode.
The deployment of distributed photovoltaic technology is of paramount importance for developing a novel power system architecture wherein renewable energy constitutes the primary energy source.
