Power Point

Solar Photovoltaic power generation shows considerable growth in the past decades. In the grid integrated PV system require MPPT controller to improve the efficiency of the power harvested from the plant due to nonlinearity nature of PV module. Among many MPPT Technique P&O has adaptive tracking, reduced oscillation around MPP. In this paper the Perturbation and Observation based MPPT algorithm with adaptive duty ratio generation is used. In this Paper in addition to PV power generation it is used for the power correction of the utility grid by injecting the power to balance the system during unbalanced load condition. Simulation of the proposed concept is run in the MATLAB 2018/Simulink environment.

New Situation

To achieve the strategic target of energy conservation and emission reduction, China is vigorously developing its large-scale and distributed renewable energy power generation industry, dominated by wind power and photovoltaic power generation. In the new situation of renewable energy power interconnection, the grid company in China must fully consider the risks caused by renewable energy when making power purchase optimization decisions. This paper sets up a power purchasing model considering the risks of the renewable energy power interconnection and testifies to the effectiveness of the model through a case study. On this basis, this paper puts forward several reasonable suggestions to help the grid company make power purchase decisions under different risk preferences.
