User comprehensive energy system optimal scheduling method considering energy storage multi-type services

Abstract

The invention discloses a user comprehensive energy system optimal scheduling method considering energy storage multi-type services, belongs to the technical field of power system scheduling, and specifically comprises the steps of proposing a concept of demand management and a logic behavior framework of the energy storage multi-type services in a long-time scale; establishing a comprehensive energy system economic dispatching model; establishing constraint conditions to enable the comprehensive energy system to meet power balance constraints, power grid exchange power, reducible load constraints and equipment operation constraints; establishing an intra-day scheduling model taking minimum total operation cost as a target; establishing intraday constraints. And an optimal month-before-daycoordinated scheduling result is obtained. According to the invention, the problem of how to realize the highest economic benefit through the combination of demand management, energy arbitrage, participation in demand response and provision of standby power by the energy storage power station is solved, the service function of energy storage of different time scales in the system is fully excavated, and the schedulability and economy of the operation of the comprehensive energy system are improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system dispatching, and in particular relates to an optimal dispatching method of a user's comprehensive energy system considering multi-type services of energy storage. Background technique [0002] Under the dual pressure of energy and environment, Europe, the United States and China have set the targets of 100%, 80% and 60% of renewable energy power generation by 2050, respectively. The integrated energy system coupled with multiple energy sources such as electric energy, thermal energy and natural gas has become a research hotspot at home and abroad because of its high energy efficiency. The user-side integrated energy system is built and operated on the user side, providing users with various forms of energy such as electricity, heat, and cold, such as the common integrated energy system in industrial parks. As an energy transfer device, energy storage can realize the thermoelectric d...
