Day-ahead optimal scheduling method for comprehensive energy system containing heat accumulating type electric heating

Abstract

The invention relates to a day-ahead optimal scheduling method for a comprehensive energy system containing heat accumulating type electric heating. The method is characterized by comprising the following steps: 1, proposing a comprehensive energy system operation optimization objective function containing heat accumulating type electric heating on a power grid interaction level according to income and operation characteristics of heat accumulating type electric heating, and determining the comprehensive energy system operation optimization objective function containing heat accumulating typeelectric heating and constraint conditions thereof; and 2, solving the comprehensive energy system operation optimization objective function containing heat accumulating type electric heating in the step 1 by adopting a simplex algorithm according to the characteristics of the model so as to obtain a planned electric heating load balance scheduling curve of the system and hourly operation output of various heating and energy storage devices. The load impact on the power grid can be effectively reduced, the peak-valley difference of the power grid is reduced, the use efficiency of electric heating equipment is improved, and the heating operation cost of a user is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of operation scheduling of integrated cooling, heating and power energy systems, and relates to a day-ahead optimization scheduling method for an integrated energy system, in particular to a day-ahead optimization scheduling method for an integrated energy system including thermal storage electric heating. Background technique [0002] Electric heating is a heating method commonly used in Nordic countries. The maintenance and use of electric heating equipment is relatively simple. By controlling the thermostat of the electric heating system, the temperature can be accurately maintained at the set temperature to achieve the purpose of heating. The international market consumption of thermal storage electric heating is mainly distributed in the Americas, Europe and Asia, and basically forms a tripartite situation. In recent years, the global thermal storage electric heating market has maintained a steady growt...
