Robust environment economic scheduling method considering multi-microgrid energy interaction

Abstract

The invention discloses a robust environment economic scheduling method considering multi-microgrid energy interaction. The method comprises the following steps: in the background of supporting the rapid development of an active distribution network by microgrids, the energy interaction among multiple microgrids is thoroughly considered; a renewable energy generation model and a cost model in themicrogrid are built; an environment economic scheduling model considering multi-microgrid energy interaction is built; the uncertainty of renewable energy and load is considered, a robust environmenteconomic scheduling model considering multi-microgrid energy interaction is built, a Latin hypercube method is adopted for sampling, and the robust environment economic scheduling model is converted to a robust certainty model; and a multi-objective chemotaxis algorithm is adopted to solve the above robust certainty model, and the Pareto optimal solution is found out. The uncertainty of renewableenergy and load prediction is thoroughly considered, the energy interaction among multiple microgrids is considered, the calculation result is closer to the actual situation, the rationality is strong, and reliable basis is provided for the economic operation of the power system.

Description

technical field [0001] The invention relates to the technical field of power system economic dispatching, in particular to a method for robust environmental economic dispatching considering multi-microgrid energy interaction. Background technique [0002] With the increasing penetration of distributed power sources (photovoltaic power generation, wind power, micro gas turbines, fuel cells, combined heat and power units, etc.) that rely on renewable energy for power generation, the active distribution network has emerged as a modern power system concept. In fact, the active distribution network is the future generation of electricity network, which involves changes in all parts of the traditional distribution network, from generation to transmission to distribution. An important part of the development of active distribution network is the microgrid, which is composed of low-voltage network, which is designed to meet the electricity, heating and cooling load demand of a town ...

Problems solved by technology

[0004] At present, in the few studies on multi-microgrid scheduling, the power interaction between microgrids is rarely considered, the pollutant gas emissions of controllable distributed power generation units in multi-microgrids are rarely considered, and the renewable energy in microgrids is rarely considered at the same time.
