Research on grid-load cooperative optimization model supporting new power system

With the large-scale integration of new energy sources into the grid, the balance between supply and demand of the power system has been challenged, and strengthening the coordination and interaction between the grid and the load has become an important means to support the safe, efficient and economic operation of the system. In this paper, we consider the demand-supply balance of the power system under a high proportion of new energy access, construct a network-load cooperative optimization model considering renewable energy, energy storage and demand response, and verify the role of demand response mechanism in dealing with the uncertainty of renewable energy so as to support the stable operation of the system through simulation of examples.
