Utilization of Waste Electricity in Microgrid Environments

Abstract

<div class="section abstract"><div class="htmlview paragraph">With the increased demand for electricity due to the rapid expansion of EV charging infrastructure, weather events, and a shift towards smaller, more environmentally responsible forms of renewable sources of energy, Microgrids are increasing in growth and popularity. The integration of real time communication between all PGSs (Power Generating Sources) and loadbanks has allowed the re-utilization of waste electricity. Pop-up Microgrids in PSPS events have become more popular and feasible in providing small to medium size transmission and distribution. Due to the differing characteristics of the PGSs, it is a challenge to efficiently engage the combined PGSs in harmony and have them share and carry the load of the microgrid with minimal ‘infighting.’ Different Power generating sources each have their own personality and unique ‘quirks.’ With loadbanks being able to perform various functions automatically by monitoring and responding to individual PGSs needs and demands, efficiency is improved and waste electricity is diverted to where it is required. The main useful functions of loadbanks mentioned in this paper represent individual desired functions. Maximizing the symbiosis in this microsystem by creating a common network and protocol environment between all components in the microgrid, adaptive automation is achieved. Refinements in translation of protocols into a standardization of SAE J1939 and CANOPEN from RS485 and MODBUS protocols contribute to the robustness of the framework including loadbanks. The Loadbank translates J1939 PGN messages on the CANBUS and reacts according to parameters from various ECM’s in the Power Generating Units, EGT, Voltage, Current and electrical load among others. Remote telemetry minimizes fault finding and common alarms are easily addressed remotely. Instituting EV charging and battery storage charging infrastructure on the backend of parasitic loadbanks in the microgrid environment maximizes otherwise wasted electricity whilst performing automated functions.</div></div>
