Abstract

The invention provides a regional integrated energy system energy storage configuration method considering an electric/thermal flexible load, and the method comprises the steps: firstly comprehensively analyzing the composition of the electric load and the thermal transmission characteristics of a heat supply system, and building an electric/thermal flexible load model; then, on the basis of the architecture of the known regional integrated energy system, establishing a model of each energy assembly, meanwhile, setting constraint conditions, including energy balance constraint, energy assembly output constraint, tie line transmission power constraint and energy storage constraint; secondly, considering system energy consumption, investment, operation and maintenance and compensation cost, and establishing an economic single-objective optimization model; and finally, based on the LINGO18.0 software, solving the established energy storage optimal configuration model to obtain the optimal output of each device and the optimal capacities of the storage battery and the heat storage tank. According to the method, the regional comprehensive energy system is subjected to energy storage optimization configuration, and the energy utilization efficiency is improved.

Description

technical field [0001] The invention belongs to the optimal configuration of an energy system, and in particular relates to an energy storage configuration method for a regional comprehensive energy system considering electric / thermal flexible loads. Background technique [0002] Traditional energy system planning and operation are limited to a single form of energy, which is not conducive to economic, environmental protection and energy cascade utilization. The comprehensive energy system integrates multiple energy sources such as electric energy, natural gas, and thermal energy in a certain area, and realizes the synergistic optimization and complementarity among various energy sources, which is conducive to improving energy utilization efficiency, promoting the consumption of renewable energy, and achieving energy conservation and emission reduction goals. is of great significance. [0003] Energy storage is an important part and key supporting technology of the integrat...
