Power demand response potential assessment method and system and related equipment

Abstract

The invention discloses a power demand response potential assessment method and system and related equipment, and the method comprises the steps: S1, constructing a special transformer user load decomposition model based on an STL algorithm, and enabling the load of a special transformer user to be decomposed to obtain a load periodic component; s2, a load curve platform power determination model based on an S-G filtering algorithm is constructed, power capable of representing a load curve platform is determined, and each local minimum value point in the load periodic component processed through the S-G filtering algorithm can represent the power of the load curve platform where the local minimum value point is located; s3, determining the real-time load power of the load periodic component at the starting time of the response by using the special transformer user load decomposition model and the load curve platform power determination model according to the starting time of the specified demand response, solving the difference value of all the load curve platform powers smaller than the real-time load power, and determining the real-time load power of the load periodic component at the starting time of the response; wherein the maximum value is the demand response potential power. The demand response potential of the special transformer user can be accurately obtained, and the management efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power intelligent management, in particular to a power demand response potential assessment method, system and related equipment. Background technique [0002] With the continuous increase of the power grid load in recent years, the peak-to-valley difference of the load continues to increase, and the peak and frequency regulation has become a difficulty in building a highly reliable power grid. In the face of short-term peak load demand, in the past, it was solved by increasing the construction of generator sets and supporting transmission and distribution networks. The utilization rate of these equipment is low and the economic benefits are not high. [0003] Demand side management is an important way of smart electricity consumption. By formulating effective and reasonable rules, without affecting the basic electricity demand of users, guide the user group to use electricity in the direction that is co...
