Adjustable Potential Evaluation Strategy of Energy Storage Participating Grid Peak Shaving Regulation in Virtual Power Plant

Virtual power plant is an important application scenario of energy storage, and energy storage also closely combines virtual power plant with power grid, bringing innovation and reform of source network load. An assessment strategy of the adjustable potential of energy storage in virtual power plant is proposed in this paper. First, an assessment model of adjustable potential of individual energy storage is constructed to achieve quantitative assessment and classification of its potential. Then, the adjustable potential evaluation method of polymer energy storage is proposed to realize the calculation of its potential. Secondly, tap the adjustable potential of the reserve potential pool and evaluate its potential to realize the reuse of energy storage resources in the reserve potential pool. Finally, the potential of adjustable polymerization in the virtual power plant is evaluated, and the response time sequence of energy storage participating in the peak clipping regulation is arranged. The calculation model and evaluation strategy proposed in this paper can evaluate the adjustable potential of individual and aggregate resources, which is conducive to improving the accuracy, rationality and effectiveness of the declared capacity of virtual power plant, and can provide theoretical reference and application guidance for virtual power plant to participate in peak cutting regulation, resource scheduling, response capacity declaration, energy storage resource management, etc.
