| Abstract: | Introduction In the process of building a new power system, renewable energy will maintain a high-speed development trend. Along with large-scale grid connection of renewable energy sources such as wind energy and photovoltaic energy, the randomness and fluctuation of its output will bring challenges to the safe and economical operation of the power system. The new energy storage system will become an indispensable resource subject to flexible regulation for the power system in the future due to its fast response ability and the effect of cutting peak and filling valley as well as the gradual reduction of its cost. Method The energy storage capacity planning was a global problem of the power system. By analyzing the renewable energy consumption rate and frequency modulation adequacy, a provincial power grid energy storage scale analysis method was proposed from the perspectives of peak shaving and frequency modulation based on the target of the lowest total cost of the system. Result Taking the actual parameters of the provincial power grid as an example, the time series production simulation software has been used to analyze the power startup mode, and the impacts of different energy storage scales on the economical efficiency of the whole society have been compared. Conclusion It shows that the consumption of renewable energy can be improved and the cost of the whole society can be reduced by adopting the appropriate scale of energy storage. The effectiveness of the method has been verified. Therefore, this work can provide some guidance for practical application. |
