ABSTRACT
This chapter presents a multilevel voltage-based coordinating controller which is responsible for sensing and measuring, switching and effectively coordinating and managing generated energy from two renewable energy sources (solar and wind). With this ability, the designed and modeled voltage-based coordinating controller is simultaneously able to perform different tasks when both renewable energy sources generate output voltages. The multilevel voltage-based coordinating controller adopts voltage-sensing and measurement techniques to operate when either or simultaneously both the solar and wind renewable energy sources output voltages. Once the output voltages from the renewable energy sources are sensed and measured, then the controller directs the switch and coordinates and manages connectivity to the load and battery energy storage system. Therefore, the multilevel voltage-based coordinating controller, using multilevel voltage sensing and measurement, effectively provides help to switch, coordinate and manage all the connected energy generators for efficient utilization. The controller is also responsible for smoothing the switching and coordination between both the solar and wind renewable energy sources, thus properly managing battery energy storage system charging during the availability of excessive output energy from either or both renewable energy sources. The proposed design and model of the multilevel voltage-based coordinating controller is simulated using the Simulink-MATLAB software, and the modeled design operation is validated based on experimental output from each stage. This approach helps to justify the proposed methodology design to model the multilevel voltage-based coordinating controller.
