Comprehensive energy optimization scheduling method for a park considering the thermal load demand response of a building

Abstract

A comprehensive energy optimization scheduling method for a park considering the thermal load demand response of a building: inputting the structure and parameters of the integrated energy system of the park according to the selected integrated energy system of the park; establishing an optimal energy system optimization plan for the park considering the thermal load demand response characteristics of the building Model; linearize the relevant nonlinear constraints in the park integrated energy system optimization scheduling model, establishing a mixed integer linear programming model and callthe corresponding solver to solve; outputting the solution results, including operating costs, host start and stop instructions, operating conditions , power supply, energy supply device energy supply command and power, centralized energy station water supply temperature, building indoor temperature. The invention fully considers the transmission loss and delay of the pipe network, the room temperature can adjust the characteristics in the comfort range, and the coupling relationship between the energy station, the energy supply pipe network, the energy supply network and the building load, can better realize the demand side management. Economically and reliably meet the user's energy needs.

Description

technical field [0001] The invention relates to a method for optimal dispatching of park comprehensive energy. In particular, it relates to a comprehensive energy optimization scheduling method for parks considering building thermal load demand response. Background technique [0002] As environmental pollution, energy depletion and other issues continue to intensify, how to improve energy utilization efficiency and build a low-carbon energy structure has become a topic of common concern around the world, and the demand for multi-type energy interconnection integration and complementary integration is increasingly urgent. The community integrated energy system (CIES) came into being under this background. The comprehensive energy system of the park refers to a complex coupling system that integrates various energy sources such as electricity, cold, heat, and gas, which is composed of a centralized energy supply network and distributed energy terminals. , which can realize h...

Problems solved by technology

Due to the neglect of the impact of energy supply pipeline transmission, the dispatch plan is quite different from the actual operation situation, and cannot meet the needs of actual dispatch; and under the time-of-use electricity price mechanism, the characteristic that the indoor temperature of the building can be adjusted within a comfortable range is not considered, which is economical.
