Description

Technical field [0001] The invention relates to the technical field of power grids, in particular to a method, device, equipment and medium for planning energy storage and output of a comprehensive energy system. Background technique [0002] With the global energy crisis and environmental problems becoming increasingly serious, it is of great significance to build a new, clean and efficient integrated energy system. In this context, an integrated energy system came into being. The integrated energy system refers to the use of advanced physical information technology and innovative management models in a certain area to integrate multiple energy sources such as coal, oil, natural gas, electric power, and heat in a certain area. Coordinated planning, optimized operation, coordinated management, interactive response, and complementarity among multiple heterogeneous energy subsystems. While meeting the diversified energy demand in the system, it is a new integrated energy system th...

Problems solved by technology

For the energy storage system planning output problem with uncertain factors, the existing technology mostly uses robust optimization to solve it, but the treatment of uncertain factors by robust optimization is too conservative, and the results obtained by optimization often make the resource utilization of the integrated energy system It is difficult to balance the operating risk and operating efficiency of the integrated energy system; the existing technology uses the value-at-risk (Value-at-Risk, VaR) or variance to optimize the risk to solve the problem of energy storage under uncertainty System planning problem, because VaR is not a consistent risk measure, and the variance also requires the probability distribution of uncertain factors to be symmetrical about the mean, so the method of using VaR or variance to optimize risk has relatively large limitations
