Coordinated Frequency Regulation of Smart Grid by Demand Side Response and Variable Speed Wind Turbines

Frequency stability of the power system is impacted by increasing penetration wind because intermittent. Meanwhile, sometimes demand side loads increase quickly to require more than total produced. So balancing active in maintain frequency main challenge high smart grid. This paper proposes coordination rotor speed control (RSC), pitch angle (PAC) and inertial (IC) turbines, together with response (DSR) participating regulation balance system. Firstly, model a single area load (LFC) obtained, which includes variable-speed turbines (VSWT) DSR containing aggregated air conditioners plug-in electric vehicles (PEVs). Then RSC, PAC IC, controls system, are introduced, respectively. Finally, these three methods for different speeds proposed. Case studies carried out LFC farm supported grid frequency. Coordination RSC combined IC used The proposed method fluctuation tested, Coordinated or can reduce peak load.
