Method of utilizing distributed energy and temporary additional electricity price to optimize control cooperatively

Abstract

The present invention discloses a method of utilizing distributed energy and temporary additional electricity price to optimize control cooperatively. The method comprises the steps of S1 determining power supply areas and a grid structure; S2 predicting the morrow RDG output and the user original load; S3 calculating the user load after the time-of-use electricity price; S4 carrying out the day-ahead optimization scheduling on the power supply areas, and starting a standby set in necessity; S5 gathering the output of the standby set; S6 carrying out the intra-day rolling calculation, namely controlling the RDG output and the user load according to the temporary additional electricity price; S7 gathering the RDG output reduction quantity and the user load reduction quantity. According to the present invention, a more flexible and changeable and more reasonable scheduling mode is provided for an active power distribution network, and fully embodies the distributed energy real-time scheduling control capability, the load flow bidirectional management capability and the distributed energy admission capability required by the active power distribution network, thereby improving the overall operation stability and robustness of the power distribution network.

Description

technical field [0001] The invention belongs to the field of dispatching operation of an active distribution network, and in particular relates to a method for collaborative optimization control using distributed energy and temporary additional electricity prices in the dispatching operation of an active distribution network. Background technique [0002] Active distribution network is a new technology developed and emerging on the basis of smart distribution network technology. Many countries have introduced this technology and carried out research. Active distribution network is the use of advanced information, communication and power electronics technology to implement active management of large-scale access to distributed energy distribution network, which can independently coordinate and control distributed generation (DG) units such as intermittent new energy and energy storage devices. , actively accommodate renewable energy and ensure the safe and economical operatio...

Problems solved by technology

Due to the randomness, volatility and uncontrollability of distributed renewable energy (RDG) output, these current demand-side response measures cannot well accommodate fluctuating renewable energy; the ideal demand response measure should be real-time electricity prices, However, the implementation of real-time electricity prices requires a sound market environment, and the large amount of data transmission requires high requirements for communication systems and smart meters

At present, my country does not have a market environment for implementing real-time electricity prices, and the implementation cost of real-time electricity prices is relatively high
