Abstract

The invention relates to an energy center-based power-gas-heat system co-scheduling method and system. The method comprises the steps of obtaining a power load prediction value, a natural gas load prediction value and a heat load prediction value of a target time segment, reported by energy centers of power-gas-heat systems; obtaining scheduling goals and constraint conditions of the power-gas-heat systems, and determining scheduling plans of the energy centers according to the scheduling goals, the constraint conditions and the obtained power load prediction value, natural gas load prediction value and heat load prediction value; and sending the scheduling plans of the energy centers to the corresponding energy centers, wherein energy converters and energy storage devices in the energy centers run according to the received scheduling plans. By adopting the scheme, the co-scheduling of the power-gas-heat systems can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of electric power system coordinated dispatch, in particular to an energy center-based electric-gas-thermal system coordinated dispatch method and system. Background technique [0002] With the increase in energy demand and environmental pressure, the third industrial revolution centered on the energy Internet is emerging. On the basis of research, scholars at home and abroad have proposed that the Energy Internet is a complex multi-network system formed by the power system as the core, renewable energy as the primary energy, and other systems such as natural gas networks and transportation networks. [0003] Under the framework of the Energy Internet, renewable energy will gradually replace traditional fossil fuels such as coal and become the main primary energy source. However, the fluctuation and intermittency of renewable energy power generation directly restrict the application scenarios and utilizatio...
