Project Background
The project addresses a prevalent technical challenge where an existingPV system's output frequently exceeds grid current limits. This bottleneckforces power curtailment, resulting in system inefficiencies and reducedrevenue. The mandate was to deploy intelligent storage to seamlessly managegrid constraints and ensure maximum PV energy utilization.
Client Demands
- Maximize the utilization of allPV-generated energy to combat high electricity costs.
- Implement a solution to bypass thephysical limitation of the interconnection point, preventing power curtailmentand generation loss.
- Ensure system safety by preventing maincircuit breaker trips or cable overloads during peak PV generation.
CESC Solution
-
Dynamic Constraint Management: ESSdynamically absorbs surplus PV energy when generation exceeds grid capacity,preventing overcurrent and curtailment.
-
Intelligent Control: Advanced EMSmonitors interconnection current in real-time, enabling precise currentlimiting and power scheduling.
-
Value Stacking: System supports secondarystrategies: peak-valley scheduling and self-consumption optimization.
Key achievements
- Risk Mitigation: Successfullyeliminated the risk of main circuit breaker trips and cable overloads at theinterconnection point.
- Maximized Efficiency: Significantlyimproved the overall utilization rate of the PV system's generated electricity.
- Ultra-Fast Deployment: Achievedrapid delivery, on-site installation, and system commissioning in a record timeof just 5 working days, demonstrating high execution efficiency.
