Evaluation method for complementarity of multi-power-supply system

An evaluation method for complementarity of a multi-power-supply system comprises the steps: dividing the multi-power-supply system into a natural resource type power supply and a conventional controllable power supply, wherein evaluation indexes for the complementarity of the multi-power-supply system are provided respectively by utilizing the natural complementarity of the natural resource type power supply and the regulation and control capacity of the conventional controllable power supply; determining the weight of each index by using an improved analytic hierarchy process; obtaining a decision matrix by using the quantitative data of the evaluation indexes, solving a weighted and normalized decision matrix by using the weights, and comparing the multi-power-supply systems from two perspectives of position and shape by using an improved TOPSIS method and combining the thought of grey correlation analysis to finally obtain a complementarity evaluation result of each multi-power-supply system.
