Design of Grid Operation Control Schemes Following Integration of New Energy Sources

With the establishment of a new type of power system based on new energy, the proportion of new energy access continues to increase, and the study of new energy grid connection has become a hot spot. This paper considers the influence of decentralized and centralized grid-connection methods on power system. This research is based on PSASP simulation platform to calculate the power flow of power system and study the power flow control scheme after grid connection. The results show that power flow can be controlled by increasing generator output and shunt capacitors during peak period. The output of the generator can be reduced during the operation of the trough section, and the shunt reactor can control the power flow. In addition, considering the decentralized and centralized grid-connection of new energy, the power flow can be controlled by reducing the output of generators and shunt reactors. This paper also considers new energy sources, which has certain practical significance under the background of "dual carbon".
