Embodiment 1

[0047] Example 1: Calculation example simulation and analysis: use the real load data of a certain city in July 2013 to perform simulation calculations, assuming that the period division and electricity price of the original time-of-use electricity price are shown in Table 1.

[0050] The accurate determination of the parameters of the CPP demand response model should be obtained through the regression fitting of the transfer rate curve in each period of the load on similar days before and after the implementation of the CPP mechanism. According to relevant literature, the lower limit of customer response to peak-valley time-of-use electricity price is about 10% of flat electricity price, the peak-to-valley transfer rate is the highest at about 8%, and the peak transfer effect of peak electricity price is 5% higher than that of time-of-use electricity price. la...

Abstract

The invention, which relates to the field of the design of the demand-response electricity pricing mechanism of the power system, discloses a design method of a dynamic peak electricity pricing mechanism. The design method comprises: (1), a peak electricity price execution period is defined; (2), a date of a peak day is determined according to a peak day trigger condition and a peak day maximum allowable day number, and a peak time period is determined by using a peak day prediction load according to a fuzzy membership analysis method; and (3), a peak electricity price decision-making model is established by considering a demand response to a peak electricity price by a user, and a reasonable peak rate is set after the analysis and comparison. The provided method is suitable for the current Chinese situation and has the high maneuverability and generalizability.

Description

technical field [0001] The invention relates to the field of power system demand response electricity price mechanism design, in particular to a design method of a dynamic peak electricity price mechanism. Background technique [0002] With the development of my country's economy, the electricity load has been increasing year by year, which has exacerbated the tense situation of power supply in special periods. In particular, the peak load in summer hits new highs repeatedly, which has a great impact on the reliability of the power grid. Under such circumstances, my country's traditional approach is to increase installed capacity and implement orderly electricity consumption. Drawing on the demand response widely used abroad, it can effectively improve the efficiency of terminal power consumption, reduce power consumption and power demand while completing the same power consumption function, and improve safety and economy. [0003] At present, the peak-valley time-of-use e...
