Rational allocation of wind power

photovoltaic and energy storage capacity is the basis for efficient utilization of new energy and stable operation of loads. Aiming at the goal of building a new power system with new energy as the main body under the “double carbon” target

a joint planning method for wind power

photovoltaic and energy storage based on the analysis of output characteristics of power units is proposed. Firstly

by analyzing the long-term operation characteristics of the power system source-load

the general operation law of source-load is revealed

the unit timing output ratio model is established

and the output characteristics of the unit are analyzed. In addition

a joint planning model of wind power

photovoltaic and energy storage capacity based on the analysis of unit output characteristics is further constructed

and the wind power

photovoltaic and energy storage capacity under the background of high proportion of new energy access to the power system is scientifically configured.Moreover

a comprehensive evaluation system for the ratio of source-storage capacity to the advantages and disadvantages of planning results is designed

and the planning results are comprehensively evaluated from the aspects of power balance

new energy consumption

and carbon emission reduction. Finally

simlation is carried out by taking a large regional power grid as an example. The results show that

the proposed model can allocate reasonable wind power

photovoltaic and energy storage capacity based on the analysis of the output characteristics of power units.
