Description
Technical Field
[0001] The present invention relates to the technical field of optimized scheduling of electrical storage loads, and specifically provides an optimized scheduling method for electrical storage loads in a virtual power plant for deep peak shaving. Background Art
[0002] In recent years, new energy sources such as solar energy and wind energy have been gradually developed. To meet the demand for the full and precise utilization of new energy sources, there is a huge demand for optimized scheduling methods during the energy supply process of new energy sources; especially with the proposal and popularization of virtual power plants, intelligent microgrids, and intelligent microgrid clusters, the simple cooperation of photovoltaic and energy storage can no longer meet the increasing demand for new energy grid connection; in the future, how to effectively, efficiently, and accurately perform deep peak shaving during the process of new energy participating in the energy supply process has become a technical problem that urgently needs to be solved;
[0003] In the prior art, a Chinese patent with the patent application number "202310618101.4" discloses that according to energy scheduling indicators, parts that do not meet the preset carbon emission indicators can be obtained. The energy consumption law is represented by energy scheduling characteristics, and the energy scheduling indicators are disassembled based on the energy scheduling characteristics. The obtained energy scheduling results can make the integrated energy system meet the preset carbon emission indicators, so as to achieve optimized scheduling with the specified carbon emission as the optimization goal, obtain the optimal operating state of each device in the integrated energy system, thereby reducing the carbon emissions of the integrated energy system, improving its environmental protection benefits, and realizing the optimization of the integrated energy system. However, the problem of economic benefits is not considered during this process. But in the actual optimization process, most use the multi-objective optimization method to optimize the electrical storage loads in the virtual power plant with economic benefits as the optimal, and do not comprehensively consider economic benefits and carbon emission indicators. Therefore, when actually optimizing the electrical storage loads in the virtual power plant, the optimization should not only be based on cost and economic value as the goal, but also consider resource and carbon-saving constraints.

[0013] Based on the distributed energy information of the virtual power plant and the total predicted amount of electricity storage load scheduling during peak shaving, construct an optimization scheduling objective function for the electricity storage load; on this basis, constraints are imposed on each type of distributed energy in the virtual power plant itself, such as constraints on the upper and lower limits of the energy storage device capacity and the upper limits of charging and discharging, and the gas turbine output meets the upper and lower limit constraints, etc.;
[0014] Taking the total predicted amount of electricity storage load scheduling during peak shaving and the power balance of the virtual power plant as the total constraint conditions for the optimization scheduling of the electricity storage load, use the particle swarm optimization method to obtain the preliminary allocation of the types of distributed energy in the virtual power plant.
[0015] According to the above technical solution, the resource consumption index includes the total consumption index of each type of distributed energy and the carbon emission index.

[0017] Calculate the total carbon emissions produced according to the preliminary allocation information of the distributed energy types of the virtual power plant, calculate the carbon emission difference from the carbon emission index in the resource consumption index by using the difference calculation formula, and determine whether the corresponding total carbon emissions in the preliminary allocation information of the distributed energy types of the virtual power plant exceed the standard;
[0018] Determine the types of optimization guiding vectors according to the consumption difference and the carbon emission difference, and guide the preliminary allocation information of the distributed energy types of the virtual power plant to be input into the corresponding optimization layer according to the optimization guiding vectors to re-optimize the preliminary allocation information of the distributed energy types of the virtual power plant.
[0019] According to the above technical solution, when the total carbon emissions corresponding to the preliminary allocation information of the distributed energy types of the virtual power plant reach the standard and there is a certain distributed energy consumption exceeding the standard in the preliminary allocation information of the distributed energy types of the virtual power plant, the type of the optimization guiding vector is the consumption optimization guiding vector;
