Description

Technical Field

[0001] The invention relates to a method, a device and a medium for allocating peak-shaving benefits of a virtual power plant, and belongs to the technical field of peak-shaving of virtual power plants. Background Art

[0002] With the continuous growth of energy demand and the increasing prominence of environmental problems, traditional energy systems are facing huge challenges. In order to meet energy demand while reducing environmental pollution, renewable energy (such as solar energy and wind energy) has gradually been integrated into the power system. However, the intermittent and instability of renewable energy has brought new difficulties to the stable operation of the power system. As an emerging energy management model, Virtual Power Plant (VPP) realizes the efficient utilization and management of decentralized energy by integrating multiple distributed energy resources (such as wind power, photovoltaics, energy storage, electric vehicles, etc.).

[0003] A virtual power plant is a comprehensive energy management system that integrates multiple distributed energy resources (DER), loads, and energy storage systems through communication technology. Its core goal is to achieve unified management and dispatch of distributed resources through optimized dispatch and coordinated control, thereby improving the reliability, economy, and environmental protection of the power system. Virtual power plants can not only provide additional power support during peak grid demand, but also perform peak load regulation during low demand periods, thereby balancing power supply and demand and reducing system operating costs.

[0004] In the operation of virtual power plants, the allocation of peak load benefits is a key issue. Peak load benefits refer to the benefits achieved in the power system through peak load measures (such as load transfer, energy storage charging and discharging, etc.). How to fairly and reasonably allocate these benefits involves the weighing of multiple factors, such as the contribution of each participant, resource type, geographical location, market mechanism, etc. Traditional allocation methods usually rely on a single evaluation indicator, which makes it difficult to fully reflect the actual contribution and benefits of each participant.

[0005] The CRITIC-GRA-TOPSIS model is a comprehensive evaluation method that combines the advantages of the CRITIC method, grey relational analysis (GRA) and TOPSIS method, and is used to comprehensively evaluate complex problems with multiple indicators and multiple objects.

[0006] Prior art, such as the Chinese patent application with patent number "CN116862551A", discloses a new energy consumption electricity price decision-making method that takes user privacy protection into consideration.

[0007] The problem with the above existing technologies is that they mainly focus on the evaluation of demand response potential and the training of pricing models based on multi-objective optimization, but when building an evaluation system, there may be a lack of clear methods and basis for the weight allocation of various indicators. Reinforcement learning algorithms require a lot of interaction and trial and error to train the model, which means that a lot of data support is required. However, in practical applications, obtaining a sufficient amount of high-quality data can be a challenge. Summary of the invention
