Abstract

The invention relates to a day-ahead optimization scheduling method of an integrated energy system considering the reconfiguration of a heating network, and belongs to the technical field of operation control of an integrated energy system. The dispatching method of the present invention establishes an objective function that minimizes operating costs; establishes constraints that include multi-type equipment output calculation equations and range constraints, heat network constraints that take into account reconstruction, power grid constraints, and power balance; through Solving the optimal scheduling model can obtain the optimal scheduling scheme of the integrated energy system for statistics and heat network reconstruction. The dispatching method of the present invention uses the heat network reconfiguration as an adjustment method in the day-ahead optimal dispatch, which can give full play to the flexibility of heat network adjustment, realize the goals of absorbing more renewable energy and alleviating grid transmission congestion, and promote comprehensive energy efficiency. The system runs efficiently.

Description

technical field [0001] The invention relates to a day-ahead optimization scheduling method of an integrated energy system considering the reconfiguration of a heating network, and belongs to the technical field of operation control of an integrated energy system. Background technique [0002] With the continuous development of social economy, the power load is increasing day by day, and the congestion problem in the power grid has attracted the attention of research and application. At the same time, the installed capacity of renewable energy continues to expand, but due to factors such as the temporal and spatial characteristics of renewable energy, power grid regulation capabilities, and grid transmission limitations, curtailment of wind and light occurs from time to time, failing to achieve the goal of renewable energy. effective application. [0003] Combined heat and power units use natural gas as the input energy to produce electricity and heat at the same time, which...
