Abstract

In order to achieve high consumption of new energy and reduce carbon emissions, this article closely links the power grid with heating network through electrolysis of water for hydrogen production and hydrogen methanation technology, as well as electric boilers and gas turbines, and other equipment. Firstly, model each unit in the integrated energy system. Secondly, introduce demand side response and divide it into price based demand response and substitution based demand response. Then, considering the energy flow characteristics of the system, constraints are imposed on the operating conditions of each unit. Finally, considering reliability, economy, environmental friendliness, and abandonment rate, a multi-objective comprehensive energy system capacity allocation strategy is established. On this basis, the commercial solver CPLEX in Matlab is used to solve the capacity configuration of the model, and the impact on the system capacity configuration with and without demand response and energy storage is analyzed. The reliability and economy of the configured capacity are verified using severe weather conditions. The results show that the capacity configuration can still have good economy and high wind and solar energy consumption rate with minimal load loss under adverse conditions.
