Under the high proportion of new energy, the power grid control demand is diverse and multi-scale, so the equipment has high redundancy and low reliability, high investment cost and large amount of inspection and maintenance. The popularization and application of integrated power control system in new energy plants and stations is an important measure to ensure the safe and stable operation of large power grids. It is of great significance to build a new energy control system with clear power and responsibility of frequency modulation and coordination of various controllable power generation units for promoting the sustainable and healthy development of new energy and realizing the strategic goal of "carbon peaking and carbon neutrality".
CYG ET integrated power control system integrates wind power/PV/energy storage AGVC, primary frequency modulation, dynamic voltage regulation, inertia support, damping control, panoramic monitoring, measurement and control of box-type substation, and protocol management. It has the performance advantages of high integration and fast response, and can greatly improve the response of the whole station while reducing the number and cost of equipment/system configuration of new energy stations.
New Energy Integrated Power Control System Solution
Overview
Features
Functions are highly integrated and redundancy is eliminated: eliminate redundancy of various types of power control equipment, centrally configure a set of power control system, and realize panoramic monitoring of new energy stations with power control acquisition terminals, which can not only replace the AGC/AVC functions of the original wind and PV monitoring system and energy storage EMS, but also have the functions of data acquisition and protocol conversion of box-type substation measurement and control
Improve reliability through measurement and control decoupling: decouple from booster station measurement and control, use special integrated acquisition terminal to access inverter controller and converter controller, collect and control the information of box-type substation unit, output GOOSE to control host and MMS to station level
Build special communication to realize fast control: build a GOOSE special network to realize fast response to control instructions
Multi-system coordination and integrated power control: support multi-system information access, such as wind-PV power prediction system, auxiliary control system, auxiliary service system and other information interaction; Docking stability control device, with stability control emergency power control, to achieve the function of replacing switching with regulation; It has the functions of primary and secondary frequency modulation, dynamic voltage regulation, inertia support and damping control
