Distribution network overcharge pricing method and a distribution network overcharge pricing system used in a distributed generation market

Abstract

The invention discloses a distribution network overcharge pricing method and a distribution network overcharge pricing system used in a distributed generation market, belonging to the technical fieldof the distribution network. Based on the postage stamp method, the total cost of power supply of each voltage level is processed to obtain the cost price of power supply of each voltage level. Basedon the position attributes of the two sides of the power generation transaction, the power supply cost price of the adjacent voltage is processed to obtain the overhead charge T1 related to the positions of the two sides of the power generation transaction. According to the total permitted income of the distribution network and the overhead charge T2 related to the positions of the two sides of the power generation transaction, calculating the overhead charge independent of the positions of the two sides of the power generation transaction. According to T1, T2 and the normal cost of distribution network, the total cost of distribution network overhead is calculated. According to the network resources occupied by the distributed generation exchange, the invention conducts the differential pricing, and solves the shortcomings of the traditional over-network pricing theory in dealing with the over-network pricing problem of the distribution network containing the distributed generation.

Description

technical field [0001] The present invention relates to the technical field of distribution network, in particular to a method for pricing network connection fee of distribution network for distributed power generation market based on the location attributes of both parties in the power generation transaction. Background technique [0002] In recent years, in order to promote the efficient utilization and nearby consumption of distributed power generation, it has become a hot spot to study the market mechanism and transaction mode suitable for distributed power generation. In the distributed power generation market, how grid companies formulate network fee pricing rules to protect their own profits while promoting the healthy development of the market is a key issue that needs to be solved urgently. [0003] Conventional network fee pricing theory is mainly used in direct electricity transactions of large industrial users, and mainly studies the allocation of network fees at...

AI Technical Summary

Problems solved by technology

The existing methods are relatively simple to calculate and the models are simple, but they are mainly oriented to the transmission network, and the focus of the research is on the source-flow traceability issue, which does not match the situation of the distribution network, and cannot accurately calculate the network fee

[0004] If the conventional method is directly applied to the distribution network, due to the weakening of the regularity of distributed power generation processing and low-voltage user load, it is difficult for the conventional power flow-based pricing method to accurately represent the network usage; in addition, the structure of the distribution network is relatively simple, such as power flow Existing methods such as tracking focus on the analysis of source-flow relationships, and are not the core issues concerned in the calculation of distribution network fees
