Gowin Energy Storage Presents Solutions to Stability Challenges in Renewable-Heavy Power Grids

The presentation discusses how Gowin Energy Storage tackles the challenge of maintaining grid stability amid increasing renewable energy penetration using their innovative grid-forming technology. The speaker outlines four sections: a case study, challenges to grid stability, Gowin's solutions, and conclusions. Renewable energy integration reduces system inertia, making grids vulnerable to disturbances that can trigger cascading failures. Three incidents illustrate this issue: an Irish power system frequency drop due to interconnector failure; Finland’s Olkiluoto Unit 3 nuclear plant turbine failure affecting Nordic grid frequency; and a UK-France interconnector trip impacting UK imports but mitigated by FFR services. Gowin identifies three key areas for stability—voltage, frequency, and power angle—and addresses these through advanced modeling techniques like affine linear modeling interaction output which adapts dynamically in real-time conditions without needing control switching during faults. This approach maintains stable connections even under extreme scenarios such as abrupt jumps or short-circuit fluctuations while avoiding overloads. Their solution demonstrates exceptional adaptability with quick recovery times post-faults and supports Blackstart applications effectively without relying on traditional rotating machinery support.
