Distributed power source optimizing configuration method based on user-side economic indexes

The invention discloses a distributed power source optimizing configuration method based on user-side economic indexes and relates to the technical field of distributed power generation in electric systems. The method includes the steps that firstly, an optimization problem mathematical model is established with the minimum user cost as a target and in combination with operation constraint conditions of all units, and then benefits and costs of a user side and a power grid side are obtained; then, capacities and power of all distributed power sources are changed and then are led into the optimization model to be calculated, corresponding benefits and costs are obtained, and the benefits and costs are used as inputs and outputs to train a neural network, and therefore the optimum distributed power source capacity and power can be obtained. The method has the advantages that economic analysis and estimation methods for a distributed power source grid-connected system based on the user-side economic indexes are provided, and the optimum configuration from which users can obtain the greatest benefits is obtained; based on the method, economic estimation is also performed on a power supply side, and the optimizing problem of the system is simplified to be a linear programming problem; accordingly, computation is simplified, a relatively comprehensive and systematic economic analysis method is provided, so the method has engineering promotional value.
