Research on Electric Power and Energy Balance of Power System with High Penetration of New Energy

In recent years., with the continuous development of new energy., the power system gradually develops into system with high shares of renewables and power electronics., which brings new challenges to the electric power and energy balance of the new power system. This paper first summarizes the operation characteristics of the new power system under the high proportion of new energy access., then summarizes the model., constraints and solution algorithm of this problem., and introduces the means of electric power and energy balance from the four dimensions of source., grid., load and energy storage. Finally., from the four aspects of theory., mechanism., technology and standard., the development demand of electric power and energy balance in power system in the future is prospected and some suggestions are given.
