Consider a solar PV plant with the following specific conditions: Analysis period: 1 year Measured average solar irradiation intensity in 1 year: 150 kWh/m² Generator area of the PV plant: 10 m² Efficiency factor of the PV modules: 15% Electrical energy actually exported by plant to grid: 135 kWh Calculate the performance ratio.
Bus Type - Known Parameter - Unknown Parameter Load Bus -P, Q - V, phase angle Generator Bus - P, V (magnitude) - Q, Voltage phase angle Slack Bus Voltage - magnitude and phase angle - P, Q
For the cut-in speed is the point at which the wind turbine is able to generate power. Between the cut-in speed and the rated speed, where the maximum output is reached, the power output will increase cubically with wind speed. Pmax directly propotional to cubical of wind speed. So, by double the speed of wind power will be increased by 8 times.
