Multi-objective optimization method for peak regulation scheduling of power system based on index linkage analysis

The invention belongs to the technical field of hydropower dispatching operation, and provides a multi-objective optimization method for peak regulation scheduling of a power system based on index linkage analysis. According to the invention, the method comprises the steps: comprehensively considering five peak regulation indexes, and introducing a linkage analysis theory in economics to perform stability test and causal relation test on a data sequence of indexes so as to effectively clarify a linkage change rule among the indexes; quantifying a mutual influence relation by adopting a regression analysis method, and further constructing the multi-index coupling peak regulation scheduling optimization model; and finally solving the model by adopting a genetic algorithm. According to the method, the comprehensive peak regulation requirements of a power grid can be described more objectively, and subjective assumptions in decisions can be reduced for dispatchers; compared with conventional different single peak
