Abstract

In future, with ultra high penetration of Wind Energy (WE) in power system, the burden of Load-Frequency Control (LFC) is switched to Wind Turbines (WT). In order to equip the WTs with LFC capability to support the grid during load-generation imbalance, sufficient reserve capacity should be procured. This paper addresses a novel fuzzy logic-based LFC scheme for inertial support offered by WTs, combined with pitch-controlled de-loading and improves transient response to achieve faster LFC action. Numerical simulations which are carried out in DigSilent PowerFactory, demonstrates the superiority of proposed methodology used in Permanent Magnet Synchronous Generator (PMSG) connected to 9-bus IEEE standard test system.
