There have been some research results in the scheduling strategy of the energy storage system of the photovoltaic charging station. It copes with the uncertainty of electric vehicle charging load by optimizing the active and reactive power of energy storage .
Various application domains are considered. Energy storage is one of the hot points of research in electrical power engineering as it is essential in power systems. It can improve power system stability, shorten energy generation environmental influence, enhance system efficiency, and also raise renewable energy source penetrations.
When the grid price is in the valley period, such as 15:00–18:00, the energy storage system chooses not to discharge regardless of the power shortage. Thereafter, the energy storage system initiates the discharging mechanism when the grid price is in the peak period starting period of 18:00.
The model is trained by the actual historical data, and the energy storage charging and discharging strategy is optimized in real time based on the current period status. Finally, the proposed method and model are tested, and the proposed method is compared with the traditional model-driven method.
Concurrently, the energy storage system can be discharged at the peak of power consumption, thereby reducing the demand for peak power supply from the power grid, which in turn reduces the required capacity of the distribution transformer; thus, the investment cost for the transformer is minimized.
The uncertainty of photovoltaic power generation output, electric vehicle charging load, and electricity price are considered to construct the IRL model for the optimal operation of the energy storage system. A double-delay deep deterministic policy gradient algorithm are utilized to solve the system optimization operation problems.
