Time-of-use electricity price design method based on model clustering method

Abstract

The invention provides a time-of-use electricity price design method based on a model clustering method. According to the time-of-use electricity price design method, a finite mixture model is adopted, and a Gaussian mixture model is adopted for clustering which is divided into clustering based on energy prices and clustering based on loads. Time-of-use electricity price design is carried out in the following two steps that (1) on a typical day, electricity prices and the loads of preset 48 clearing time periods are clustered on the basis of the Gaussian mixture model, the clearing time periods can be allocated to distribution models different in probability respectively, the distribution models take each of the clearing time periods as a different charging stage which is a peak load stage, a flat load stage or a valley load stage; (2) different types of time-of-use electricity prices are derived through different combinations of multiple types of clearing regions, and final time-of-use electricity prices are obtained by guaranteeing that a supplier has the same earnings when a unified electricity price is adopted and the time-of-use electricity prices are adopted. According to the time-of-use electricity price design method, the finite mixture model is applied so as to cluster local customers and charging prices at a flat rate are used for deriving the time-of-use electricity prices. According to changes of the energy prices and needs, measurement is carried out independently.

Description

technical field [0001] The invention is a time-of-use electricity price design method based on a model clustering method, which belongs to the innovative technology of the time-of-use electricity price design method based on the model clustering method. Background technique [0002] Power demand side management achieves the purpose of alleviating power shortages and improving power utilization efficiency by improving terminal power consumption efficiency and improving power consumption methods. It has been widely used at home and abroad. Electricity price is one of the important economic means to implement power demand side management, and it is also the most efficient means. Time Of Use pricing (TOU) is a price mechanism that can effectively reflect the difference in power supply costs in different periods of the power system. Reasonable structure and method of power consumption can realize cutting edge and filling valley. [0003] For a long time, suppliers have conside...

AI Technical Summary

Problems solved by technology

[0003] For a long time, suppliers have considered various costs and adopted a unified electricity price. However, it is very challenging to directly derive the time-of-use electricity price based on the wholesale price. There are also factors such as grid investment costs and operating costs that make it difficult to quantify the time-of-use electricity price.

At present, the formulation of time-of-use electricity prices is mostly based on experience, without much theoretical support and standard formulation methods
