| Popis: | This paper describes the performance of grid-integrated Hybrid Renewable Power System (HRPS). It establishes a Wind Turbine (WT), a Microturbine (MT) and a battery which support the dump load, Local Grid (LG) and/or grid integrated domestic load. DC/DC converters are used to join WT, MT and battery in a common DC bus. The output of DC bus is synchronized to the local grid through hysteresis controlled three-phase voltage source converter to increase the continuity of power. The proposed HRPS is working under switching control algorithm. According to the proposed algorithm, the wind energy is controlled via optimal torque based maximum power point tracking method, and is used the primary energy source to meet the load demands. The MT is added as a secondary system to confirm continuous power flow. The battery is utilized as a high energy density and/or back device to keep the DC-bus voltage constant. The dump load is used to consume any excess power inside the system. To verify the effectiveness and performance of proposed system, a test bed is created using Matlab/Simulink based on recorded wind speed and load profile of a small community at Peshawar, Pakistan region. Various results are obtained to show proposed power system performance in terms of grid synchronization, voltage and frequency stability, power quality and load tracking. |
