Establish a capacity optimization configuration model of the PV energy storage system. Design the control strategy of the energy storage system, including timing judgment and operation mode selection. The characteristics and economics of various PV panels and energy storage batteries are compared.
The main structure of the integrated Photovoltaic energy storage system is to connect the photovoltaic power station and the energy storage system as a whole, make the whole system work together through a certain control strategy, achieve the effect that cannot be achieved by a single system, and output the generated electricity to the power grid.
In the default condition, without considering the cost of photovoltaic, when adding energy storage system, the cost of using energy storage system is lower than that of not adding energy storage system when adopting the control strategy mentioned in this paper.
By comparing the three optimal results, it can be identified that the costs and evaluation index values of wind-photovoltaic-storage hybrid power system with gravity energy storage system are optimal and the gravity energy storage system is economically viable.
The main advantage of the integrated Photovoltaic energy storage system is that it can combine the advantages of the two single parts to overcome its own shortcomings. For example, the output of the PV system is not balanced, and its volatility and intermittentness are greatly affected by the environment.
