Benefits
Real-time Adaptive Control
Based on dispatch instructions, power generation equipment output is adjusted as a technical means to achieve continuous steady-state regulation and rapid coordinated control of active/reactive power of plants. This addresses the intermittency and unpredictability of renewable energy.
Frequency Active Support
Utilizing fast frequency and voltage regulation, as well as inertia active support technology, high-end hardware enables active support on a dynamic timescale of seconds and milliseconds.
Intelligent Coordination Regulation
With intelligent algorithms for station clustering and multi-station coordination, large-scale wind, solar, and energy storage systems are optimally managed for efficient and smart operation, effectively minimizing unwanted renewable energy curtailment.
Typical Cases
Three Gorges Ulanqab Wind-Solar-Storage Integrated Project
This pioneering 2GW hybrid wind-solar-storage integrated project comprises 1.7GW of wind capacity, 300MW of solar capacity, and a 550MW/1100MWh energy storage system. SIFANG’s multi-source coordinated control system employs a three-tier architecture—consisting of a centralized control center, coordination controllers, and station controllers—to enable the precise dispatch of wind, solar, and storage units. It provides grid-support capabilities for hybrid renewable plants, including peak shaving, load balancing, power smoothing, and primary frequency regulation.
