Problems solved by technology

The traditional peak-valley time-of-use electricity price produces an "over-modulation" effect, which leads to an increase in the operating cost of conventional power sources and reduces the utilization rate of power generation resources

Embodiment Construction

[0029] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0030] The present invention proposes a dynamic peak-valley time-of-use electricity price method for improving the new energy consumption capacity, which mainly includes the following main steps:

[0031] Step 1: Forecast the previously predicted system load curve and new energy output curve, calculate the system net load curve, and use the FCM (fuzzy C-means) clustering algorithm to perform cluster analysis on the system net load curve to obtain the membership of peaks, flats and valleys in each period degree, according to the principle of the maximum degree of membership, the peak and valley periods are divided, and the peak and valley time-of-use electricity price is obtained.

Abstract

The present invention discloses a dynamic state peak-valley time-of-use tariff method for improving new energy absorption capability. The method provided by the invention is characterized by dynamically guiding user rational electricity consumption, building a demand response assessment model taking a dynamic state peak-valley price into account and simulating that a user predicate the changing of force according to the new energy to dynamically respond so as to prompt the new energy absorption capability. The method comprises: (1) performing cluster analysis of the current payload of a system and dynamically dividing a peak balka period to obtain the peak-valley time-of-use tariff; (2) determining the classification of each data sample according to the maximum membership principle through adoption of a FCM cluster algorithm to perform effective peak balka fuzzy classification of the system payload of each period; and (3) building a demand response assessment model taking the dynamic state peak-valley price into account to take the set operation cost and the minimum wind abandoning as an optimal object, and introducing corresponding constraints to obtain corresponding system wind abandoning electric quantity. The dynamic state peak-valley time-of-use tariff method for improving the new energy absorption capability has a wide range of application.

Description

technical field [0001] The invention relates to a method for dynamically adjusting the division of peak and valley time periods, in particular to a dynamic peak and valley time-of-use electricity price method for improving new energy consumption capacity. Background technique [0002] With large-scale wind power, photovoltaic and other new energy sources coming online for power generation, the randomness and volatility of new energy output has brought huge challenges to the operation of the power system. When the output of new energy exceeds the carrying capacity of the grid, in order to meet the real-time balance between power generation and load of the system, curtailment of wind and light will be unavoidable. [0003] At present, countries all over the world are actively exploring measures to accommodate new energy sources. In terms of policies, the United States has established a number of bills to increase funding for new energy technologies, reduce dependence on fossi...
