Abstract:

With the current electric power reform and the continuous promotion of the electric power market, the development of virtual power plant has become a key part of them. It is also the main concentration part of the complex factors of market transactions, and the flexible load and clean energy also bring great challenges to the virtual power plant. Considering the operation characteristics of different types of users’ flexible load, this paper analyzes and models the characteristics of industrial, commercial and household loads, fully mobilizes some controllable resources within the virtual power plant to interact, and combines the operation characteristics of wind power, photovoltaic power and gas turbines to establish a purchase and sale optimization model for virtual power plant considering the deep interaction of diversified flexible loads. In addition, with the development of clean energy and the challenge of uncertainty brought by photovoltaic and wind power, a scenario data-driven distributional robust model with two-stage variable for power purchase and sale optimization of virtual power plant is proposed, which is solved by column and constraint generation algorithm. The effectiveness of the optimization model is verified by the analysis of examples.

Key words: virtual power plant, diversified flexible load, distributionally robust operation, coordinated optimization
