Description
Technical Field
[0001] The present invention relates to the technical field of electric energy dispatching, and in particular to a multi-strategy coupled virtual power plant dispatching system and method. Background Art
[0002] Multi-strategy coupled virtual power plant scheduling refers to the management and operation arrangements of virtual power plants by combining and synergizing multiple different scheduling strategies. Multi-strategy coupling means the comprehensive use of price-based strategies (such as time-of-use electricity price strategies), power balance-based strategies, resource optimization allocation-based strategies, and forecast-based strategies (such as forecasts of load and energy output).
[0003] However, the traditional multi-strategy coupled virtual power plant scheduling may have delays in information transmission between various parts, affecting the real-time adjustment and precise execution of the strategy. At the same time, sometimes it may only focus on the optimization of local strategies, but it is difficult to achieve the global optimal scheduling of the entire system. Some of the prediction models it relies on may not be accurate enough, resulting in deviations between strategy formulation and actual conditions, which greatly reduces the scheduling effect of virtual power plant scheduling.
[0004] Therefore, in order to overcome the above-mentioned defects, the present invention provides a multi-strategy coupled virtual power plant scheduling system and method. Summary of the invention
[0005] The present invention provides a multi-strategy coupled virtual power plant dispatching system and method, which is used to analyze the real-time operation data of each data source collected, so as to accurately and effectively determine the power forecast demand of the distributed user-side energy storage power station. Secondly, the power forecast demand is analyzed according to the multi-dimensional optimization target, so as to accurately and effectively determine the multi-dimensional dispatching strategy under the multi-dimensional optimization target, thereby providing data support for the effective dispatching of power plant electricity, and the obtained multi-dimensional dispatching strategy is coupled and coordinated to lock the optimal balance point of the multi-dimensional optimization target. Finally, a dispatching plan is generated according to the obtained optimal balance point to achieve effective retrieval of power plant electricity, and the generated dispatching plan is dynamically optimized to ensure the dispatching effect and accuracy. The multi-strategy coupling algorithm enables the virtual power plant to maximize the use of distributed user-side energy storage power station resources and optimize the overall operating efficiency while ensuring economic benefits. The intelligent dispatching strategy and collaborative dispatching mechanism ensure the efficient utilization of distributed energy storage resources and the stable operation of the system.
