Regional distributed energy system optimization method based on demand distribution continuous condition

Abstract

The invention relates to a regional distributed energy system optimization method based on a demand distribution continuous condition, and the method comprises the following steps: (1) determining anenergy supply radius, and building a continuous demand distribution model; (2) establishing a neighborhood scale regional distributed energy system model comprising a supply side pipe network, a demand side pipe network and a transmission and distribution side pipe network; (3) establishing a non-linear optimization model of regional building group energy interconnection and intercommunication considering the supply side and the demand side at the same time, the non-linear optimization model taking the primary energy saving rate as an objective function and taking energy balance and equipmentcapacity as constraints; and (4) solving the nonlinear optimization model to obtain the optimal building mixing ratio, the optimal energy supply technology combination and the energy supply amount ofeach type of energy per hour. Compared with the prior art, the energy-saving performance of the system is considered from the perspective of the space structure, collaborative optimization of the energy supply strategy and the building mixing ratio is effectively achieved, and the application effect of the regional distributed energy system is improved.

Description

technical field [0001] The invention relates to a method for optimizing a regional energy system, in particular to a method for optimizing a regional distributed energy system based on continuous demand distribution. Background technique [0002] At present, my country's economy has shifted from a stage of high-speed growth to a stage of high-quality development. As a barometer of economic development, my country's energy consumption structure is also in a period of deep adjustment. Generally speaking, the growth rate of industrial energy consumption has slowed down or even decreased in total, while building energy consumption has shown a trend of both total and proportion growth with the improvement of living standards and living requirements. The above-mentioned development trend has also been confirmed by the historical evolution of urbanization, industrialization and modernization in developed countries. For this reason, building energy conservation will become the mai...
