Abstract

The invention discloses an independent micro-grid capacity configuration containing photo-thermal power generation. The method specifically comprises the following steps: step 1, establishing an independent hybrid energy micro-grid model; step 2, setting an optimization target and constraints; and step 3, determining a coordination scheme under the priority of each optimization target. According to the independent micro-grid capacity configuration method containing photo-thermal power generation, a three-objective optimization model for capacity configuration of an independent hybrid energy micro-grid containing photovoltaic, photo-thermal, fan, energy storage and diesel generator is established by taking comprehensive economic cost, power supply reliability and renewable energy utilization rate as optimization objectives; an improved multi-target grey wolf optimization algorithm is used for solving the model, and the obtained configuration scheme has high feasibility and effectiveness.

Description

technical field [0001] The invention belongs to the technical field of power system optimization, and in particular relates to a method for configuring the capacity of an independent microgrid including photothermal power generation. Background technique [0002] Since the expansion of the power grid in areas with inconvenient power supply such as remote mountainous areas or independent islands has high requirements on the geographical environment, and the economic cost is also relatively high, and with the continuous maturity of renewable energy power generation technology, the effective use of abundant scenery resources in mountainous areas and islands The construction of an independent microgrid that complements multiple energy sources is of great significance to solve the problem of power supply in areas where power supply is inconvenient. One of the important tasks in building an independent microgrid is to optimize the capacity of various renewable energy sources in th...
