Stored energy operation control method based on electricity spot price prediction and tracking and system thereof

Abstract

The invention provides a stored energy operation control method based on electricity spot price prediction and tracking and a system thereof, and belongs to the field of stored energy coupling electricity trade under electricity spot market. Assuming a real-time market is a balancing market before one hour and temporarily ignoring the duration of charge and discharge of energy storage device, the electricity price at time T is the real price tracked in real time and the electricity price after time T is the forecast price. Judgments are made respectively on the basis of the predicted price of electricity at different times. The stored energy operation control method based on electricity spot price prediction and tracking and the system thereof are mainly used for guiding the energy storage unit to participate in the electric energy trade of intraday market and the electric auxiliary service of real-time market. According to the result of the electricity price forecast, the system guides the energy storage device to choose an appropriate time node for the charge and discharge operation. The system always judges the present moment and outputs the action of the energy storage device after one hour and the matching adjustment of the power transaction plan, which provides the maximal economic benefits of energy storage device in electricity spot market for users and electric companies.

Description

Technical field [0001] The invention relates to the field of energy storage coupled electric energy trading under electric power spot market conditions, and in particular, to an energy storage operation control method and system based on electric power spot price prediction and tracking. Background technique [0002] Electric energy has the characteristics of instantaneous transmission and cannot be stored on a large scale. Therefore, during the real-time operation of the power system, it is necessary to maintain the "source-grid-load" power balance. The spot market and ancillary service market in the modern power market are based on the need for power balance. Established. The spot market is divided into day-ahead market, intraday market, and real-time market; ancillary services are a special power commodity that run through every trading period of the electric energy market. For the power consumption side, ancillary services can ensure good power quality and Power supply ...

AI Technical Summary

Problems solved by technology

[0004] The present invention proposes an energy storage operation control method and system based on power spot price prediction and tracking, which solves the problem that the energy storage energy management system in the prior art cannot dynamically determine the energy storage operation mode according to the electricity price fluctuating at any time
