Stability Enhancement of the Net-zero Carbon Microgrid

The microgrid (MG) concept has been effective in creating aggregations of renewable energy resources (RESs)—generation, storage and loads—for resiliency, in the form of energy...y security. Net-zero-carbon microgrids (NZMGs) can contribute to these commitments by transitioning to renewable and non-carbon-based generation. Over 60 GW of RESs are recently involved in the KSA electricity generation sector. The success of MGs in bringing energy security to a wide range of customers has been exemplified during power disruptions and extended outages due to extreme weather events, cybersecurity attacks, and equipment failures. MGs have an opportunity to meet the climate change challenges and contribute to a carbon-free power delivery system. The transition to Net-zero starts within MGs themselves by replacing fossil fuelled generators with renewable generation. NZC is achieved by supplying the loads within the MG boundaries from generation based on RESs, balanced and firmed by means of electrical storage and aggregations of other DERs, including controllable loads such as Constant Impedance Loads (CILs) and Constant Power Loads (CPLs). As electronic loads increase, the proportion of CPLs will rise. The CPLs characteristics disturb the NZMG stability. Aligned with the KSA Vision 2030 and our center goal, a new control technique will be proposed to improve the stability of NZMG in the presence of CPLs. Load droop control will be designed to reimburse the CPLs instability problems. The NZMG including CPLs will be modelled and implemented in real time digital simulator (RTDS). The proposed controller will be tested and investigated in RTDS.
