New energy local consumption system suitable for nearby transaction of producer and consumer of power distribution network

Abstract

The invention discloses a new energy local consumption system suitable for power distribution network producer and consumer nearby transactions. The system is characterized by comprising the following steps: market admission of producers and consumer owning conventional loads, air conditioners and distributed photovoltaic power generation; the electricity price bidding decision of the consumer who obtains the right to enter the market; forming of a market transaction result based on a multi-round clearing method of electricity price bidding of the consumer; a deviation punishment method of the deviation based on the transaction result; market settlement based on the first round of deviation checking; a shared energy storage mechanism facilitating local balance of deviations; and second-round market settlement based on the shared energy storage transaction result and the second-round deviation check. According to the new energy local consumption system, the power distribution network producer and consumer can automatically report the electric quantity and electricity price bidding decision in the distributed transaction market, the nearby transaction of energy and the local consumption of new energy are promoted, and the excitation compatibility of individual benefits and system benefits is realized.

Description

technical field [0001] The invention relates to the technical field of electric power distributed transactions, in particular to a new energy on-site consumption system suitable for nearby transactions of distribution network producers and consumers. Background technique [0002] Under the background of building a new power system with new energy as the main body, distributed photovoltaic and wind power have achieved rapid development, which further increases the uncertainty on the distribution network side. At the same time, the wide access of high-proportion distributed new energy sources makes the traditional distribution network power end users change from single power consumers to producers and consumers, with broad adjustment flexibility and adjustment potential to be tapped. However, under the existing mechanism of "spontaneous self-use, surplus to the grid", the uncertainty of the distribution network further converges to the main network, which seriously affects the...

Problems solved by technology

However, under the existing mechanism of "spontaneous self-use, the surplus is connected to the grid", the uncertainty of the distribution network will further converge to the main network, seriously affecting the supply and demand balance of the system

In addition, the inherent hierarchical structure of the power system insulates end-prosumers from upper-level market signals, and end-users lack sufficient professional knowledge and risk tolerance to deal with complex rules of market transactions and fluctuating price risks

In the existing research, there is a lack of a market mechanism and trading system that encourages the terminal producers and consumers of the distribution network to realize automation and high-frequency transactions nearby, so as to realize the local consumption of new energy
