Virtual power plant rolling scheduling technology considering temperature control load polymer

Abstract

The invention provides a virtual power plant rolling scheduling method considering mass temperature control load aggregation, which comprises the following steps: counting temperature control loads on each bus of a virtual power plant, carrying out cluster clustering on each temperature control load according to demand information of each temperature control load, and calculating parameters of an aggregator; then, according to prediction information of a temperature control load aggregation result, renewable energy sources and various types of electricity prices, establishinga virtual power plant optimization scheduling model considering temperature control load aggregators , obtaining a pre-optimization result of rolling scheduling through solving, and obtaining reference power of each aggregator ; allowing each aggregator to decompose and optimize the reference power and distribute the reference power to each temperature control load in the aggregator to obtain an actual power demand of each temperature control load in the aggregator; and formulating a final rolling scheduling plan according to the actual power requirements of all the temperature control loads. By implementing the method, coordinated scheduling of mass temperature control loads in the virtual power plant can be achieved, and the method has the advantages of being high in calculation efficiency, wide in compatibility and high in practicability.

Description

technical field [0001] The invention relates to the technical field of scheduling control of virtual power plants, in particular to a rolling scheduling method of virtual power plants considering temperature-controlled load aggregators. Background technique [0002] Temperature-controlled loads have great potential to improve the operating efficiency and economy of power systems. However, the large number, small scale and variety of temperature-controlled loads bring challenges to the centralized management and optimal dispatch of the power system. Using virtual power plant technology can aggregate and manage massive temperature-controlled loads, fully tap the scheduling potential of massive temperature-controlled loads in the power system, and solve the "dimension disaster" problem brought by massive temperature-controlled loads to power system managers. In view of this, the present invention proposes a virtual power plant rolling scheduling method considering massive temp...

Problems solved by technology

[0004] In the above prior art, only a small number of flexible devices are modeled one by one. However, in the actual system, the temperature-controlled loads have the characteristics of large number, small capacity, and different parameters. If the temperature-controlled loads are managed one by one , virtual power plant managers will face the "curse of dimensionality" problem
