Abstract
The invention discloses a virtual power plant optimal scheduling method and device, and belongs to the technical field of source-network-load interactive operation scheduling and control, and the method comprises the following steps: obtaining day-ahead prediction data and short-time prediction data; and constructing a day-ahead-real-time market double-layer optimization scheduling framework based on the day-ahead prediction data and the short-time prediction data. Aiming at the problem that a virtual power plant with multiple physical entities participates in optimal scheduling of a day-ahead-real-time market, a double-layer distributed optimal scheduling framework is provided for improving the optimization solution time, and a distributed day-ahead optimal scheduling model with the maximum benefit of the virtual power plant as a target is established on the upper layer based on day-ahead prediction data; for the volatility of renewable energy output, a lower layer establishes a real-time scheduling model aiming at following a day-ahead scheduling scheme based on short-time prediction data, an introduced ADMM algorithm is adopted, a centralized optimization problem is converted into a distributed optimization problem, the communication requirement is low, and the calculation speed is high.
Description
technical field [0001] The invention belongs to the technical field of source-network-load interactive operation scheduling and control, and more specifically relates to a virtual power plant optimization scheduling method and device. Background technique [0002] In recent years, virtual power plants have reduced user demand on a large scale to achieve large-scale power saving, and then achieved the goal of generating the same amount of electricity as new power plants. Virtual power plants have huge potential in grid-connected consumption of distributed power sources and user-side demand response. Application prospect. [0003] However, there are some difficult problems in the power coordination management of each physical entity in the virtual power plant and its participation in power system scheduling as a whole. Therefore, it is of great research significance and application value to study the hierarchical scheduling strategy of the virtual power plant. Contents of th...
