Embodiment Construction

[0094] In this example, if figure 1 As shown, a peak load adjustment method considering time-of-use electricity price and incentive compensation is firstly to solve the optimal time-of-use electricity price based on the time-of-use electricity price optimization model considering the interests of the grid side and the user side, and solve the time-of-use electricity price through the third-order elasticity matrix The load curve under the electricity price; secondly, the time period of the load under the time-of-use electricity price is re-divided by the fuzzy clustering method, and the peak period is divided; finally, the peak load adjustment measures are determined based on the proportional allocation principle, and the user power shortage cost is determined. The peak incentive price can provide technical support for the actual peak load demand side management; specifically, it is carried out according to the following steps:

Abstract

The invention discloses a peak load adjustment method considering time-of-use electricity price and incentive compensation. The steps include: 1 establishing a time-of-use electricity price model considering the objective functions of the power grid side and the user side to obtain the optimal time-of-use electricity price; The load under the time-of-use electricity price is re-divided into time periods, and the peak hours are further divided by fuzzy clustering; 3. Based on the principle of proportional sharing, the peak load adjustment strategy is determined; 4. The load transfer rate is calculated through the price elasticity matrix and the load curve under the time-of-use electricity price; 5. Calculate the peak incentive price based on the user's power shortage cost. The invention establishes a peak load adjustment model based on the time-of-use electricity price by studying the impact of different demand-side response strategies on user loads, and further reduces peak loads on the premise of ensuring user satisfaction, thereby improving system reliability.

Description

technical field [0001] The invention relates to the field of power system demand side response, in particular to a peak load adjustment method considering time-of-use electricity price and incentive compensation. Background technique [0002] Demand response refers to the behavior of electricity users to shift or reduce load in response to electricity prices or incentive signals. Time-of-use tariff (TOU) is an important part of the demand response strategy. The implementation of the TOU tariff strategy can not only delay the investment in the power grid but also improve the stability of the system operation, it is widely used in the electricity market. However, for special time periods, even if the peak-valley time-of-use electricity price is implemented, the peak-time load (that is, peak load) in the peak time period is still relatively high. The existence of peak load not only reduces the utilization rate of power equipment, but also has an adverse effect on the safe and ...
