Time-sharing electricity price pricing method based on control parameters and feedback adjustment

Abstract

The invention relates to a time-sharing electricity price pricing method based on control parameters and feedback adjustment. The method comprises the following steps: 1, according to historical data, obtaining a price demand response matrix describing electricity consumption rules of users; 2, setting target values of the control parameters; 3, according to current target values of the control parameters, calculating an electricity price of each period; 4, according to the electricity price of each period, obtained in the third step and the price demand response matrix, calculating an electricity quantity of each period when the control parameters are at the current target values so as to obtain actual values of the control parameters; and 5, determining whether gaps between the current target values and the actual values of the control parameters satisfy set requirements, if so, taking the electricity price of each period at present as an optimal pricing scheme, and otherwise, after the target values of the control parameters are adjusted, returning to the third step. Compared to the prior art, the method has the following advantages: the control is flexible and accurate, the power supply income is remarkably improved, the total electricity consumption amount is effectively controlled, the peak-valley load gap is narrowed, and the like.

Description

technical field [0001] The invention relates to the field of electric power technology, in particular to a time-of-use electricity price pricing method based on control parameters and feedback adjustment. Background technique [0002] The most typical time-of-use pricing strategy is the peak-valley pricing strategy, which has an obvious peak-shaving and valley-filling effect, making the distribution of electric energy more even and reasonable in time. There are many studies on this aspect in the existing literature, for example: based on the assumption that the total power consumption remains unchanged before and after the strategy adjustment, a time-of-use pricing strategy is formulated; assuming that the electricity price in normal periods is equal to the annual average electricity price before the strategy adjustment, and studying the impact of electricity prices on The impact of electricity consumption; the research is carried out based on the assumption that the element...

Problems solved by technology

However, the assumptions relied on in the above literature are debatable, and there are the following deficiencies: it is unreasonable to keep the total power consumption unchanged, and the adjustment of pricing strategy will cause changes in user response, and the total power consumption will be different from the previous one; It is unreasonable to preset the segment electricity price as the annual average electricity price before adjustment, because the constraints are artificially added; the characteristic limitation of the relationship function between electricity price and electricity is also not considered, which will reduce the degree of freedom of the problem
