Distributed new energy heat supply system optimization scheduling method and device

Abstract

The invention belongs to the technical field of energy scheduling, and provides a distributed new energy heat supply system optimization scheduling method and device. The method comprises the following steps: obtaining related operation data of an energy system, an energy storage system and a demand side load, and obtaining source storage load data; based on the source storage load data, initializing optimization scheduling parameters and the relation and the flow direction of energy among the energy system, the energy storage system and the demand side load at different moments, judging whether the energy system, the energy storage system and the demand side load are in a dynamic balance state or not, and obtaining thermal interaction data at different moments; according to the source, storage and load data, initializing an optimization scheduling parameter and an electric energy balance equation, and calculating the electric energy flow direction and size at each moment in a heat-to-electricity mode to obtain electric power interaction data among the source, the storage and the load at different moments; and summarizing the thermal interaction data and the electric power interaction data among the source, the storage and the load at each moment in the set time period, and taking the summarized data as an optimization scheduling scheme of the set time period interval.

Description

technical field [0001] The invention belongs to the technical field of energy scheduling, and in particular relates to a distributed new energy heating system optimal scheduling method and device. Background technique [0002] The statements in this section merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] Aiming at some disadvantages of traditional central heating, a new idea of ​​distributed heating is proposed in the prior art. Distributed heating directly meets the needs of users in a small area (such as a residential area, a commercial office building, etc.), without the need to build large centralized heat source stations and lengthy heating pipe networks, and instead uses a variety of renewable The small heat source station of energy has a small heating radius, occupies less land, and has less investment. It can implement personalized customized services according to the specific conditions of...
