Bus 6 Bus 3 Bus 4 Bus 1 Load 1 G1 Load 3 Student(s): Anshuman Vaidya, ECE Department Faculty Advisor(s): Dr. Badrul Chowdhury, Dr. Jonathan Kimball, ECE Department Bus 2 Bus 5 Load 2 • APPROACH • First the Maximum Power Point is tracked for the given amount of available Solar power. • Then the system is operated at point slightly lower than the MPP so as to provide a control over a control over the active power production. • Power converters used in the system can provide/absorb reactive power as and when needed. • APPROACH • Determine the wind speed in the area and calculate the maximum power that can be captured by the wind turbine. • Keep the pitch angle as low as possible abiding the rpm limit of the motor. • Calculate various parameters like TSR(λ), Cp(λ,β). • Determine the Active and Reactive power capability of the DFIG used by identifying it’s machine parameters and rated operating values. OBJECTIVES • In this project, new converter control techniques will be developed to improve grid compatibility of solar photovoltaic plant (PVP) and wind power plants (WPP). • The aim is to enable PV and wind power systems with voltage and frequency regulation capability by providing active and reactive power reserves in PVP and WPP. • One objective is to determine the max available active and reactive power of PVP/WPP and the associated capability curves. • BACKGROUND • Increasing penetration of renewable sources weakens the grid because of intermittency. • Ancillary support is needed to counter large penetrations. • Renewable energy sources like WPP and PVP have untapped capability to support the grid by voltage and frequency regulation. • Capability of a PVP or WPP system can be analyzed and matched according to the need. RESULTS Power output curve vs Pitch angle and Speed Win speed 14 m/s 12 m/s Active and Reactive Capability Curve with different wind speeds PhotoVoltaic Plant (PVP) System Wind Power Plant(WPP) System • FUTURE WORK • Active and reactive power capability information of renewable power plant would help the plant operator to take an informed decision at the time of crisis. • Converter control techniques would be developed in the later stages of this work which would help in frequency and voltage regulation of the grid.
