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.
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 .
Therefore, an optimal operation method for the entire life cycle of the energy storage system of the photovoltaic-storage charging station based on intelligent reinforcement learning is proposed. Firstly, the energy storage operation efficiency model and the capacity attenuation model are finely modeled.
When a large number of EVs are charged simultaneously at an EV charging station, problems may arise from a substantial increase in peak power demand to the grid. The integration of an Energy Storage System (ESS) in the EV charging station can not only reduce the charging time, but also reduces the stress on the grid.
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 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.
