Implementing Frequency Regulation Capability in Solar Photovoltaic Power Plants
نویسندگان
چکیده
Photovoltaic power plants pose some challenges when integrated with the power grid. The PV plants always focus on extracting the maximum power from the arrays. This makes the PV system unavailable for helping in regulating the grid frequency as compared to conventional synchronous generators. A new technique for tracking a pseudo-maximum power point for creating power reserve is presented. This will help provide fast acting power to respond to rapid load changes in a manner analogous to the inertia of a rotating machine. The system is implemented in a two stage power conversion model and has been developed in Simulink/Matlab. A GE-PV 200 solar array has been used for this purpose. The new technique is discussed in detail and simulation results are provided.
