Hardware Implementation of Hybrid AC-DC Power System Laboratory Involving Renewable Energy SourcesDue to shortage of traditional energy resources and concerns of their environmental impacts onour society, the utilization of renewable energy sources such as wind, photovoltaic and fuel cellsare now very important for future power systems. These resources will need to be implementedin large scale aided by energy storage systems and accordingly they will present new challengesto future engineers in the field of energy systems. Hybrid AC-DC power system are morereliable than the traditional AC distribution system. When a fault occurs in an AC side of a grid,the ‎ C grid can be disconnected from the AC grid, continuing service to customers on the DC Dside. Also, the available resource on the microgrid can be utilized to help restore service to theAC side in a variety of ways.‎The hybrid power system utilizes several new techniques for improved restoration features suchas advanced protection, enhanced operation and optimum control. In this paper, we present thedevelopment of methodologies for integrating most popular renewable energy sources andstorage systems. Along with coverage of these topics in the class progress, students will beinvolved in developing laboratory experiments to examine and verify the concepts covered in theclassroom.This effort involves the following development:  The development of a platform to emulate and control the wind power based on the wind- power equation and characteristics of wind pattern and turbine design to obtain the maximum power at different rotary speeds of generator for various wind speeds.  The development of experiments along with implementation for maximum power point tracking (MPPT) techniques for photovoltaic (PV) energy sources.  Development of procedures for controlling the Voltage of the DC bus in isolated DC grids and hybrid microgrids  Development and integration of real time test setups including the utilization of environments such as DSP/dSpace/matlab/simulink based control interfaces.  Development of procedures for integrating Bi-directional DC-DC converters for the storage systems (batteries) and its performance evaluation.  Development of bidirectional energy conversion in dc microgrid for the power sources with high voltage ripple.  Development of integration procedure of software phased locked loop to recognize the phase and frequency of the AC grid and apply it into the control system of 3 phase inverters.  Development of procedures for bi-directional control of active and reactive power flow in a three phase grid-tied voltage and current source inverters in hybrid micro grids.  Develop procedures for applying energy transfer strategies in DC grids using renewable energy sources and storage systems to show the students how to maintain the balance of consumption and energy generation.  Develop procedures for security and dependability improvement for hybrid power system protection.Students will achieve high level of knowledge by integrating the above hardware-softwaretechniques to achieve hands on experience through laboratory experiments. The students will begraded on their involvement in the laboratory and report on the evaluations and analysis of theresults.
