Research on the Design Methodology of Integrated Energy System Evaluation System Considering Different Weighting Rates of Multiple Indicators

Regarding the integrated energy system centered on a dual-source efficiency heat pump coupled with biomass-air energy, this paper proposes a design method for the evaluation system of the integrated energy system under the consideration of multiple indicators with different weighting rates, in order to solve the problems such as the difficulty of the capacity configuration, the evaluation complexity of later stage, and the difficulty of quantification. By combining the engineering practice, different capacity allocation schemes of renewable energies are given, and based on this, the simulation examples of eight sets of capacity allocation schemes under the dynamic change of the weighting rates of five indicators are established with full consideration of multiple indicators, such as renewable energy consumption rate, carbon emission, investment and operation economy, distribution grid capacity, COP and so on. The results show that the algorithm can calculate the comprehensive performance of different capacity allocation schemes under the changing weights of indicators, and the evaluation system helps to determine the best renewable energy capacity allocation scheme according to the engineering practice.
