With the rapid development of the economy and the depletion of conventional energy sources, it is imperative to vigorously develop new energy sources. The new energy power generation industry, represented by wind power and photovoltaic power generation, has gradually become industrialized and scaled up. Its grid-connected operation effectively relieves the load pressure that the grid is subjected to. However, the output of new energy sources is random and uncontrollable. After grid connection, it will increase the uncertainty of the system and affect the stable operation of the system. Therefore, how to safely and effectively absorb intermittent renewable energy has become a major practical problem facing the new energy power system. Current research results at home and abroad mainly focus on the optimal design of the power supply on the supply side, the optimal dispatch strategy on the grid side, and the demand side. Response mechanism and planning management. Studies involving the stability and economics of power system operation and the joint planning of source and load resources are still in the preliminary stage. Therefore, the establishment of a new energy power system energy balance, economy and the joint planning model of the source and the load provide a theory for the country to promote supply-side structural reforms, formulate phased energy-saving emission reduction targets, renewable energy power supply construction standards and electricity price subsidies and other related policies.
