Virtual power plant is an integrated technology and operation mode to realize air-conditioning load participating in power system operation, further benefitting low carbon renewable energy applications. However, the principle of multi-system coupling in central air-conditioning poses a challenge to normal load regulation. Besides, the uncertainties of demand-side resources bring risks to the operation of virtual power plant. In this paper, the regulation characteristics of central air conditioning are obtained by experiment, while the potential of central air conditioning is quantified by a thermodynamic model, further resulting in the central air conditioning could be transformed into a virtual unit model. Then the dynamic capacity optimization strategy is formulated based on the risk measurement theory, while the generation task decomposition strategy is also formulated based on the equal increase rate criterion, thus forming a two-tier operation strategy of virtual power plant. Finally, illustrative case study is constructed to quantitatively analyze the power generation capacity and effectiveness of the virtual power plant. The effectiveness and practicability of the proposed strategy is also verified to benefit low carbon energy applications.

Abstract Due to technological advancements in recent years, distributed energy resources (DER) applications have become more prevalent in households and businesses, including various renewable energy applications. While the virtual power plant (VPP) can integrate energy storage, flexible loads and DER, etc., it can support the power grid operating stability and security. Therefore, more and more researchers give their attention to VPP and advise on their optimization. This paper states the VPP concept from other researchers’ studies and provides a detailed explanation. Meanwhile, some typical VPP projects worldwide are also presented. In addition, some potential challenges and future development advice in the VPP studies are also presented.
