Dispatching method and system for energy center in industrial park

Abstract

The invention discloses a dispatching method and system for an energy center in an industrial park. The method comprises: establishing an optimized operation model inside an energy center in an industrial park under a deterministic parameter and carrying out calculation to obtain an operation cost; according to the operation model, establishing a robust model and an opportunity model of thermal load uncertainty and electric load uncertainty by using an IGDT; on the basis of an inputted equipment thermal load parameter, an inputted equipment electric load parameter, and a controllable load parameter as well as the operation cost and operation cost range information, solving a robust model and an opportunity model respectively by using a CPLEX solver, thereby obtaining a robust dispatching method and an opportunity dispatching method; on the basis of the robust model, obtaining a robust dispatching strategy for resisting thermal load and electric load fluctuation; and on the basis of the opportunity model, obtaining an opportunity dispatching strategy for having an opportunity to obtain better operation costs. Therefore, a reference is provided for a risk avoidance type decision maker and a risk preference type decision maker.

Description

technical field [0001] The invention relates to the field of power system operation optimization, in particular to a scheduling method and system for an energy center in an industrial park. Background technique [0002] In terms of heat supply, the promotion of combined heat and power generation and heating electrification can greatly improve energy utilization efficiency, and is an effective way to realize demand-side electric energy substitution. Combined Heat and Power generation (CHP) is an advanced energy conversion device based on the principle of energy cascade utilization, which uses high and medium temperature steam to generate electricity, and low temperature waste heat to supply heat to residential buildings. Heat pump is a new energy technology that can obtain low-level heat energy from air, water or soil, and provide high-level heat energy for residents through electric energy. The heat pump is stable in operation, easy to start and stop, and has high heating ef...

Problems solved by technology

For energy centers in industrial parks, on the one hand, it is difficult to obtain the probability distribution of thermal loads and electrical loads; on the other hand, for energy centers with sufficient funds, decision makers can accept relatively conservative decision-making results; It is hoped to obtain better operating costs, but the above methods are difficult to meet the requirements of energy center operation optimization in industrial parks
