Description

technical field [0001] The invention belongs to the technical field of integrated energy distribution systems, and in particular relates to a power optimization method for the interactive operation of an integrated energy distribution system and an upper-level power grid. Background technique [0002] Social development has a strong dependence on energy. Unfavorable factors such as the depletion of fossil energy and the pollution to the environment make people have to seek clean energy to replace traditional fossil energy. As the research on central air-conditioning and gas turbines continues to mature, the coupling degree of various energy systems is also increasing. Traditional energy systems are planned and operated separately, and the coupling between various energy sources is not fully considered. The integrated energy distribution system (integrated energy distribution system) The energy distribution system (IEDS) considers the coupling relationship between various ene...

Problems solved by technology

The traditional power grid can only achieve this goal by increasing or decreasing the load, but the adjustment of the load involves the user side, and there are certain difficulties in achieving this goal. However, IEDS can achieve the comprehensive energy distribution system by adjusting the energy distribution relationship of the energy station. Interact with the upper-level power grid to adjust the power, so as to meet the demand of the upper-level power grid for the power consumption of IEDS

However, there are few related technical studies in this area, and the safe operation of the natural gas network and the feasible regulation domain of the interactive power between the integrated energy distribution system and the upper-level power grid are rarely considered in the relevant research, and it is easy to have a large difference from the expected results.
