Active support type wind and light storage integrated power control system and energy distribution method thereof

Abstract

The invention discloses an active support type wind and light storage integrated power control system and an energy distribution method thereof. The system comprises an NSEARTSuite middleware which carries out the data reading and writing through a unified access interface, and an application software layer. The application software layer comprises an acquisition device, main control equipment which is used for acquiring a local control instruction and a remote scheduling instruction, calculating plant-level target active power and reactive power after algorithm model control operation, and issuing the set active power and reactive power to the execution equipment, monitoring equipment and an energy management system which is communicated with the station controlled equipment through the Nsealink converged communication system. The energy management system automatically decomposes active / reactive target values issued by the main control equipment to different energy systems in real time. The problems that a traditional new energy field station is complex in control framework, low in efficiency and the like are solved, a unified data communication platform and a unified real-time database platform are adopted, and operation of the wind-solar power storage field integrated power comprehensive control system is achieved.

Description

technical field [0001] The invention relates to the technical field of new energy power generation, and more specifically relates to an actively supported wind-solar-storage integrated power control system and an energy distribution method thereof. Background technique [0002] With the development of renewable energy such as wind power and photovoltaics, the penetration rate of renewable energy power generation has increased rapidly, and its impact on power grid operation has gradually increased. New energy represented by wind power and photovoltaics is gradually becoming an important energy resource in my country, playing an important role in meeting energy demand, improving energy structure, reducing environmental pollution, and protecting the ecological environment. [0003] The existing new energy station network communication is relatively complicated, and the traditional IEC-104 communication protocol is adopted for the dispatching system, the IEC-103 or 61850MMS comm...

AI Technical Summary

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to provide an active support type wind-solar-storage integrated power control system and its energy distribution method, so as to solve the problem that the coordination between the existing new energy station equipment can only be carried out by means of communication, while Affect the speed of frequency modulation and voltage regulation, and reduce the reliability of the system. Based on the concept of data sharing, a unified data communication platform and a unified real-time database platform are adopted to realize the operation of the integrated power control system of wind, wind, storage and electric field
