| contents | Integration of Inverter-based Resources (IBRs) such as solar-powered plants which lack the intrinsic characteristics such as the inertial response of the traditional synchronous-generator (SG) based sources presents a new challenge in the form of analyzing the grid stability under their presence. For example, solar power is available for approximately from 9 AM-5 PM. However, the result of the rise in power consumption after 6 PM and the reverting back to the non-renewable source of power generation during that period puts immense stress on the grid, testing the ramp limitations of the SGs. Failure to meet the required power demand due to SG ramp limitations leads to failure of the power grid and other catastrophes. Numerous mitigation techniques exist in order to address the ramping issues with adding the energy storage elements (ESE) to the grid being one. ESEs have higher ramping capabilities compared to the traditional SGs. Also, the ESEs can store the energy and supply it to the grid when required making them extremely responsive to high ramp situations. However, the rate of degradation of the ESEs is faster than the SGs. This raises an important issue of addressing the degradation of the ESEs while meeting the required power demand objectives and constraints. This work proposes a battery degradation-aware model predictive energy management strategy and it is tested via a numerical simulation on multiple physical systems such as Shipboard Power Systems (SPS). Moreover, the risk arising due to the fault in the IBR is also studied by means of a numerical simulation. Overall, the goal of this study is to make the existing power grid more robust, resilient, and risk-free from component degradation and eventual failures. |
