Comprehensive energy balance scheduling method for industrial park

Abstract

The invention discloses a comprehensive energy balance scheduling method for an industrial park, and the method comprises the steps: step 1, obtaining the starting moment of an optimization period, and determining the optimization period and each group of scheduling intervals; step 2, obtaining a topological structure and subsystem information of the energy system; obtaining the real-time price ofeach energy source, and calculating the average price of the energy sources in each scheduling interval; step 3, obtaining historical data of a demand side load; establishing a load prediction model;predicting future cold / heat and electricity demands by using a load prediction model; step 4, establishing an energy supply and storage model of each subsystem; step 5, determining an optimization variable; setting an objective function; setting constraint conditions; obtaining an optimized scheduling model; and step 6, calling a genetic algorithm to solve the optimal scheduling model to obtain ascheduling result. Compared with an existing scheduling method, the method is closer to the actual system operation condition, and the demand side load data prediction accuracy can be improved; And the energy storage strategy is more accurate and flexible. And the selection of the objective function is more flexible.

Description

technical field [0001] The invention relates to the field of energy technology, in particular to a comprehensive energy balance scheduling method in an industrial park. Background technique [0002] my country currently has 347 national-level industrial parks, 1,167 provincial-level industrial parks, and 10,000 prefectural-level industrial parks. Industrial parks have needs for water, electricity, heat, and gas, and also discharge sewage, solid waste and other waste. The traditional park energy supply method has certain disadvantages due to industry barriers, early planning and other issues, which lead to problems such as low energy utilization, poor economic benefits, and large environmental pollution. [0003] At present, most of the energy dispatching methods for industrial parks focus on the dispatching of the power grid, and there is still a lack of efficient and reliable dispatching methods for the integrated energy of distributed systems such as cold, heat, and elect...
