Simulation of wind only system with battery energy storage and dump load

It has become imperative for the power and energy engineers to look out for the renewable energy sources such as sun, wind, geothermal, ocean and biomass as sustainable, cost-effective and environment friendly alternatives for conventional energy sources. However, the non-availability of these renewable energy resources all the time throughout the year has led to research in the area of hybrid renewable energy systems. Since hybrid power systems are mostly used in remote areas where grid-connection may be unavailable; these systems must be self-sufficient in frequency and voltage control. In this paper, other power elements are introduced to provide reliable service to the system load and simulated the wind turbine generator with DL showing graphs for frequency, voltage and active and reactive power for the elements of the system. These elements are called balancing mechanisms, as they balance the system´s power output to match the load consumption. Fuel Cells, batteries, dump loads (DL), and fossil fuel based generation have been used as balancing mechanisms. Hybrid power system is simulated and the performance analysis is done in a user friendly MATLAB/Simulink environment. The results show that with DL frequency regulator helps in maintaining system frequency and the voltage variations are reduced. The main objectives of the model implementation are controlled flow of active power. The wind turbine kept under electrical load without losing synchronism with the help of Battery energy storage and the Dump load.
