The following is the analysis of summer conditions: the difference between real-time building load and PV power generation is less than 18 kW between hours 0:00–5:00 and 11:00–15:00 on July 15th, and the system imports electricity from the utility grid to charge the battery.
The main components of the typical distributed photovoltaic-battery energy storage system (PV-BESS) include the utility grid, a solar PV system, an energy storage system, and building loads. The system's schematic diagram is shown in Fig. 1.
PV systems combined with energy storage systems are expected to improve the overall performance of the system and relieve the grid distribution stress by employing an optimal battery charging and discharging schedule.
In daytime (10–17 h), energy storage systems are charged from the PV panel, 20% of load is injected into grid by PV panel, and remaining power is used to charge the battery. The perfect balance of scheduled generation and scheduled load results in nominal frequency. Any deviations from schedule will result in deviation from nominal frequency.
Optimal power flow is performed for upstream grid, grid with BES, and for grid connected PV system with BES for various load and generation patterns. BES system was able to regulate the frequency with proper selection of charging and discharging mode based on UI cost.
The use of Photovoltaic (PV) generation forecasts in economic load dispatching control (EDC), which includes the unit commitment (UC) of conventional power plants, is essential to ensure the economic performance and the reliability of power systems.
