Abstract

The invention discloses an electrical-gas combined system reliability judgment method based on electrical combined optimization power flow. The method comprises the following steps of modeling the equipment reliability of the electric power-natural gas combined system through a multi-state model; constructing Energy bidirectional flow and energy optimal configuration of electric power and naturalgas in the electric power-natural gas combined system through electrical combined optimization power flow, conducting simulation processing on all possible states of the electric power-natural gas combined system through a time sequence Monte Carlo method by means of an objective function and constraint conditions of the objective function, and acquiring the electric power-natural gas combined system; judging reliability parameters of the natural gas combined system whether to be reliable or not according to the reliability parameters, and then taking measures to improve the reliability of theelectricity-gas combined system. According to the method, the reliability of the power-natural gas combined system is accurately judged under the condition of considering the electrical combined optimization power flow, so that a scheduling mechanism can be helped to improve the power-natural gas combined system; Reliability of natural gas combined system.

Description

technical field [0001] The invention relates to a reliability processing guarantee method of a power grid system, in particular to a method for judging the reliability of an electric-gas combined system based on an electric combined optimization flow, and belongs to the field of comprehensive energy system operation and reliability analysis. Background technique [0002] As an efficient and clean fossil fuel, natural gas has been widely used in recent years. According to a report released by the China Electricity Council, in 2016, the power generation of gas-fired units reached 1.833×10 8 MWh, compared with 2015, an increase of 12.81% over the same period. In addition, with the maturity of power-to-gas technology, excess electricity can be converted into hydrogen through the process of electrolysis of water or further methanized by using power-to-gas equipment, and injected into the natural gas transmission system, thus realizing the energy exchange between the power system...
