Hybrid energy system consists of two or more forms of energy sources. This dissertation presents a control of a micro-grid which is fed by hybrid energy sources. It is fed by wind energy, the conversion of which is done via a setup which has a doubly fed induction generator (DFIG) and a battery bank with a common DC bus. It is also fed by solar energy, the conversion of which is done using a solar photovoltaic (PV) array. The common DC bus is used for evacuating this power via DC-DC boost converter. Vector control of LSC is used for managing the voltage and frequency. The setup works when the wind power source is inaccessible. The algorithm for both energy blocks contains maximum power point tracking (MPPT). The simulation for the said mode has been developed using MATLAB. A prototype is finally implemented. The study of the said model is then made for various inputs under various load conditions. It is seen that the power quality remains within the satisfactory breaking points at high terminals.

Pressure and Torque control in Brake InertiaDynamometer (BID) is necessary to ensure the testing brake system reliability. The main objective of using the Dynamometer limits certain aspects such as reduced man power, variable inertia, accurate response, limited to a small test space, parameters can be store and analysed. A dynamometer is a device for measuring force, torque, or power. The power produced by engine, motor can be calculated simultaneously by sensing of torque and rotational speed. The added advantage in using a BID is that, it can be able to simulate all kinds of vehicles such as HCV, LCV, SUV and Sedan which provides the maximum and minimum limits in each parameters by directly ensuring the safety. The control of Pressure and Torque is done 'n' number of times to make sure it is more reliable as well as to meet the required consumer specification. This paper consists of real time data acquisition process which uses a simulation tool named NI LabVIEW.
