Method for intelligently making peak shaving and load shifting strategy for power customers

Abstract

The invention discloses a method for intelligently making a peak shaving and load shifting strategy for power customers, and the method comprises the steps: carrying out the clustering of load curves of a regional power grid in a certain time through employing a two-step clustering algorithm, and obtaining a regional power grid clustering result, wherein the regional power grid clustering result comprises a clustering center curve and clustering details; carrying out the dividing of the peak and valley of the load curves of the regional power grid, and carrying out the matching of a power customer curve at a corresponding date through combing with the regional power grid clustering result; carrying out the clustering of the power customer load curve of a certain type of regional power grids in the same period at the peak and valley through employing the two-step clustering algorithm, obtaining the clustering result of the power customer, wherein the clustering result comprises a clustering center curve and clustering details; and constructing a peak shaving and load shifting index of the power customer according to the normalized mean value of the power customer clustering center curves of the regional power grid and the similarity between the regional power grid and the corresponding power customer clustering center curve. The method is high in practicality, and irons out a defect that the recommended peak shaving and load shifting strategy of the power customer does not accord with the actual condition because only the curve shape or load absolute value is considered.

Description

technical field [0001] The invention relates to the field of electric power technology, more specifically, a method for intelligently formulating a strategy for power customers to cut peaks and fill valleys. Background technique [0002] Power plants generate electricity continuously around the clock. If the electricity generated is not used, the energy used for power generation will be wasted. The power generation capacity of a power plant is usually fixed and not easy to change, but the peak of electricity consumption is usually during the day, resulting in insufficient electricity during the day, and the low point at night, and the excess electricity that cannot be used is wasted. In response to this phenomenon, the power The system moves a part of the peak load to the low valley period at night, so that the excess electricity at night is used, and the purpose of energy saving is achieved. The above is the peak-shaving and valley-filling in the electric power field. The ...
