As an important platform that connects energy production and consumption, the power grid is the key part of energy transformation, and it takes the major responsibility for emission reduction (State Grid Cooperation and of China 2021). Distribution networks are the intermediate link between production and demand.
With its bi-directional and flexible power characteristics, energy storage can effectively solve the security and stability issues brought by the integration of distributed power generation into the distribution network, many researches have been conducted on the urban distribution networks.
Finally, the proposed optimal scheme is evaluated using an IEEE standard case, and the economic benefits of the system are analyzed. Integrating distributed power generation into distribution networks can be an effective strategy to mitigate carbon emissions and realize the full use of clean energy.
