TIE-LINE FREQUENCY BIAS CONTROL OF PV-WIND HYBRID POWER SYSTEM FOR MICRO GRID APPLICATION

The solar and wind power technologies being well established, penetration of these Renewable Energy Sources (RES) into the grid is increasing progressively. The large scale interconnected PV-Wind hybrid power farms (PVWHPF) are usually located away from the load center depending on the geographical conditions. There by, inter area power dispatch is required in interconnected power system with a proper Tie-line control. The load frequency Control (LFC) of interconnected RES generation is gaining importance in Micro-grid application. A at tie-line frequency bias control of interconnected two-area PVWHPF is investigated in MATLAB, Simulink. The framework of LFC system should be able to handle complex, high degree, wide distribution of load and power generation to ensure the successful operation of LFC by maintaining generation load balance. This paper ad-dress a droop characteristic based at tie-line frequency control to minimize frequency deviation, power exchange over the tie-line. The proposed control demonstrates good tie-line frequency control of interconnected PVWHPF.
