Microgrid real-time optimization scheduling method based on day-ahead economic optimal operation plan

Abstract

The invention discloses a micro-grid real-time optimization scheduling method based on a day-ahead economic optimal operation plan, and the method sequentially comprises the following steps: S1, building power generation unit models which comprise power generation models of a gas turbine, a wind driven generator and a photovoltaic power generation unit; s2, making a day-ahead economic optimal operation plan, and constructing an optimization model comprising load balance constraints and equipment operation constraints; and S3, performing real-time correction and rolling scheduling based on the real-time optimization scheduling of the micro-grid of the day-ahead economic optimal operation plan to ensure that the generating capacity and the load are kept balanced during operation and improve the operation economy of the system. The micro-grid real-time optimization scheduling method based on the day-ahead economic optimal operation plan has the advantages that the economy of the day-ahead operation plan can be kept to the maximum extent under the condition of meeting power balance through a two-stage real-time correction and rolling scheduling technology on the basis of the day-ahead economic optimal operation plan.

Description

technical field [0001] The invention relates to the technical field of microgrid economic dispatch, in particular to a microgrid real-time optimal dispatch method based on a day-ahead economic optimal operation plan. Background technique [0002] With the rapid development of the energy industry and the diversified development of energy utilization forms, various forms of clean energy power generation technologies such as wind, light, gas, and biomass energy have been more and more effectively applied. One of the typical utilization methods is the distributed power generation technology represented by wind power generation, photovoltaic cells, micro gas turbines and storage batteries. The access of distributed power sources breaks the top-down power supply mode of the traditional power grid. Distributed power sources can supply energy to the loads in the surrounding area, and can also sell electricity to the power grid, thus forming a micro-grid that can interact with the la...
