Abstract

The invention discloses a method for adaptive optimization of power supply decision-making of a photovoltaic building power supply system. The method comprises the three steps including quantification of preventive and post-accident power supply control costs of the photovoltaic building power supply system, optimization model building and solution and simulated analysis on the optimization model. Based on the coordinated optimization theory, a mathematical model for adaptive optimization of power supply decision-making of the photovoltaic building power supply system, and based on the sensitivity of cost to parameter, the optimization algorithm of the optimization direction is guided to solve the model, so that the economical efficiencies of various power supply control schemes are quantified, and sensitivity analysis on the influence from the preventive and the post-accident controlled quantity to the power supply decision-making is carried out so as to provide decision-making reference to economical operation and reliable power supply of the photovoltaic building power supply system. Therefore, the method provided by the invention is a simple and efficient decision-making optimization method.

Description

technical field [0001] The invention relates to a method for self-adaptively optimizing the power supply decision-making of a photovoltaic building power supply system, which belongs to the economical operation and reliable power supply technology of the photovoltaic building power supply system. technical background [0002] In order to meet the load power supply demand of photovoltaic building power supply system, its power supply mode can be divided into two types: preventive control and post-accident control from the control point of view, where preventive control corresponds to the power supply of photovoltaic building power supply system under the grid-connected mode of large power grids, and post-accident control Corresponding to the use of various power supply methods within the photovoltaic building power supply system to participate in the power supply of the photovoltaic building power supply system under the island mode. Distributed generation and outages can int...
