Triangular comprehensive evaluation-based optimal configuration method of novel energy supply system

Abstract

The invention provides a triangular comprehensive evaluation-based optimal configuration method of a novel energy supply system. The method comprises the following steps: firstly, selecting the load power loss rate, the load heat loss rate, the system annual cost and the energy surplus rate as evaluation indexes in three aspects of the power and heat supply stability, the economy and the new energy utilization condition of the novel energy supply system, building a triangular comprehensive evaluation model, and setting the area of the triangular comprehensive evaluation model as a target function of the optimal configuration method; then building an optimal mathematical model of the novel energy supply system according to the constraint conditions by taking the maximum area of the triangular comprehensive evaluation model as a target; and finally, using a hierarchical iteration algorithm to solve an optimal configuration scheme of the novel energy supply system, and verifying the correctness and feasibility of the optimal method through actual calculation examples. The optimal configuration scheme can meet the rigid requirements of power and heat in remote regions, and is beneficial to the economic operation of the energy supply system and the efficient utilization of renewable energy sources.

In addition, the existing multi-objective algorithm generally converts the multi-objective problem into a nonlinear single-objective optimization problem based on the linear summation of multiple objectives or based on the fuzzy membership function; but in these two methods, the linear weighting coefficient depends on the empirical design , has great uncertainty, and the selection of fuzzy membership function is very complicated. How to make a reasonable comprehensive evaluation of multiple performance indicators of the new energy supply system determines the execution process of the optimization algorithm and the quality of the optimization results. satisfaction level
