Abstract
Integrating flexible load within modern power systems substantially benefits grid management, resource optimization, and system efficiency. By harnessing the capabilities of flexible load, power system operators can effectively address challenges arising from intermittent renewable energy sources and unpredictable fluctuations in electricity consumption. This research presents an innovative approach to mitigate issues related to wind power forecasting errors in power systems with high wind energy integration. The proposed solution involves integrating flexible load potential within the Load Frequency Control (LFC) scheme, enabling efficient management of grid power imbalances. To evaluate the effectiveness of this approach, a comprehensive simulation study is conducted using the DigSILENT Power Factory software. The simulation model combines thermal, gas turbine, and wind energy systems with a dynamic flexible load model integrated into the LFC operation. This enhances active power balance regulation, reduces dependency on traditional generators, and boosts economic efficiency.
