Industrial park comprehensive demand response scheduling method based on multi-energy cooperation

Abstract

The invention discloses an industrial park comprehensive demand response scheduling method based on multi-energy cooperation. The method comprises steps that an operator executes day-ahead load prediction and reports the day-ahead load prediction to ISO or bids to the power market; the operator obtains a load reduction index from the ISO or the market clearing result; the operator determines a scheduling plan by solving a comprehensive demand response optimization model and informs a consumer and the CCHP of the result; if any consumer or CCHP cannot respond according to an instruction, the operator rearranges the scheduling plan, otherwise, the response is executed; on the second day, the consumer adjusts the load demand, reduces the power load or increases the heat and cold loads at theappointed time, and the CCHP correspondingly adjusts the yield to balance the load. The method is advantaged in that various interactive modes such as interruptible load, multi-energy demand coupling,multi-energy supply and demand interaction and the like are provided, the selectable space of a user is increased, scheduling means of the operator is increased, comprehensive energy consumption management is realized, and scheduling cost is reduced.

Description

technical field [0001] The invention relates to the technical field of comprehensive demand response scheduling, in particular to a multi-energy coordination-based comprehensive demand response scheduling method for industrial parks. Background technique [0002] Thanks to advances in smart grid technology and advanced metering facilities, the flexibility of consumers' electricity demand has increased significantly. Many Demand Response (DR) mechanisms have been studied to achieve the goals of peak shaving or renewable energy consumption. [0003] In recent years, the development of combined heat and power and integrated technology has promoted the evolution of demand response in smart grids to integrated demand response (Integrated Demand Response, IDR) in integrated energy systems (Integrated Energy System, IES). Like electricity demand, consumer energy demand can be flexible and adjustable if given the right incentives. Therefore, a reasonable IDR mechanism becomes an i...

Problems solved by technology

It has not yet involved the interaction between different types of energy demands and the unified optimal scheduling of generalized demand-side resources

[0011] 2. At present, most studies believe that CCHP and flexible load are two independent methods to achieve optimal scheduling, that is, the former is not considered as a demand-side resource that can be used for IDR purposes. It is usually assumed that CCHP is owned by VPP or microgrid operators, and demand response Still an interaction between consumer and operator without the involvement of other actors

However, the interaction between the demand side of one energy system and the supply side of another energy system, for example, how changes in heat demand affect electricity supply, has not yet been studied

[0013] 4. The current research usually regards the user's flexible needs as a resource that can be directly controlled, and has not studied how to design and provide incentive compensation in the IDR plan
