State Grid Shanghai Electric Power Company Applies for Patent on Blockchain-Based Virtual Power Plant Optimization Dispatch Method in Electricity-Carbon Coupling Market

On April 7, 2025, financial news outlet JINRONG reported that the State Intellectual Property Office of China showed that State Grid Shanghai Electric Power Company had applied for a patent titled "Optimization Dispatch Method of Virtual Power Plant Based on Blockchain in Electricity-Carbon Coupling Market," with publication number CN119762278A and an application date of December 2024. This patent aims to solve the optimization dispatch challenges of virtual power plants in electricity-carbon coupling market environments. It leverages blockchain technology to improve resource utilization efficiency and ensure market fairness and data credibility.

The patent abstract details a five-step method:

First, step S1 establishes a committee comprising all participating entities within the virtual power plant. This committee consists of a primary representative node and multiple other member nodes, providing an organizational structure for subsequent optimization dispatch and decision-making. The primary representative node plays a crucial role, responsible for model solving and result distribution. Other member nodes participate in verification and voting, ensuring fairness and transparency.

Next, step S2 establishes a virtual power plant optimization dispatch model. This model, the core of the method, considers various factors such as power supply and demand balance, carbon emission targets, and the interests of different participants. Its objective is to find the optimal dispatch scheme, maximizing energy utilization efficiency while meeting carbon reduction goals. Model creation requires sophisticated mathematical calculations and algorithm design to ensure accuracy and effectiveness.

Third, step S3 is the crucial model-solving step. The primary representative node solves the established model outside the blockchain using the Karush-Kuhn-Tucker (KKT) conditions. KKT conditions are commonly used to solve nonlinear programming problems, finding the optimal solution of the objective function while satisfying constraints. Solving outside the blockchain likely improves computational efficiency, given the relatively slower speed of blockchain computations.

Fourth, step S4 involves storing and broadcasting the solution to the blockchain. After obtaining the optimal solution, the primary representative node encrypts it before storing it on the blockchain, ensuring data security and preventing tampering or leakage. Following storage, the node broadcasts the result to all other member nodes for verification.

Finally, step S5 is the verification and voting stage. All other member nodes verify the received information through the blockchain's verification mechanism, ensuring data integrity and correctness. After verification, they vote on the correctness of the optimal solution. If the vote confirms the solution's correctness, the virtual power plant executes it; otherwise, a new primary representative node is selected, and the process returns to step S3 for resolution. This mechanism effectively prevents incorrect decisions and ensures overall reliability.

Compared to existing technologies, this patent application offers significant advantages. It more effectively optimizes resources in the peak-shaving and carbon-coupling market while ensuring fair participation and data credibility. Traditional virtual power plant dispatch methods may suffer from inefficiencies, information asymmetry, and opaque decision-making. This patent application, using blockchain technology, effectively addresses these issues, improving resource utilization efficiency, reducing carbon emissions, and promoting the green transformation of the energy industry.

The core innovation is the application of blockchain technology. Its decentralized, transparent, and tamper-proof nature makes it ideal for building trust mechanisms and protecting market participant interests. In virtual power plant optimization dispatch, the blockchain records all transactions and decision-making processes, ensuring traceability and transparency, effectively preventing fraud and improving market efficiency.

This patent application not only demonstrates State Grid Shanghai Electric Power Company's technological innovation capabilities but also reflects the nation's emphasis on energy transformation and green development. As the electricity-carbon coupling market continues to develop, virtual power plant optimization dispatch will become increasingly important. This blockchain-based optimization dispatch method promises a more efficient, secure, and reliable solution for virtual power plant operation, promoting the green and low-carbon development of the energy industry.
