Abstract

The invention provides a virtual power plant operation modeling method, which comprises the following steps: 1) a robust mixed integer linear programming model with profit maximum of a virtual power plant in participation in power market operation as a target function is built, and a robust interval optimization method is adopted in the mathematical model to handle uncertainty of the electricity price; 2) with an upper limit and a lower limit of the electricity price as a boundary, the robust interval model is built; 3) an iteration number, an iteration step size and a robust coefficient are set; and 4) IBM CPLEX software is used for acquiring the optimal bidding result of the virtual power plant in participation in market operation. Compared with the prior art, the virtual power plant operation modeling method has the advantages of good economic benefits, high calculation efficiency and the like.

Description

technical field [0001] The invention relates to a virtual power plant operation modeling method, which belongs to the field of virtual power plant operation. Background technique [0002] In recent years, with the ever-increasing demand for energy and the increasing shortage of fossil fuels, countries around the world are actively advocating efficient and environmentally friendly energy supply forms, and many challenging new energy supply methods are emerging worldwide, the common form of which is aggregation distribution Formal renewable energy participates in the operation of large power grids and power markets. Among different types of renewable energy, wind power is the most reliable and stable form of organization. The capacity of wind turbines in the European Union increased rapidly from 1.743GW in 1990 to 194GW in 2010. At the same time, about 12% of the world's energy is provided by wind power. Due to the randomness and intermittency of renewable energy itself, the...
