Control Strategy for a Small-Scale Microgrid Based on Battery Energy Storage System-Virtual Synchronous Generator (bess-Vsg)
… which means Battery Energy Storage System-Virtual Synchronous Generator, the frequency can be controlled to the nominal value faster and more smoothly when there is a fluctuation in the PV power generation and/or load change, leading to higher stability and robustness.</p> <p>This thesis …

Power System Frequency Control and Stability Analysis With Increasing Renewable Energy Penetration Level
… units and the replacement of traditional synchronous generators, the issues associated with the deteriorated performance of power system frequency regulation and potential grid frequency instability become more significant. In this dissertation, the inertial control algorithms are …

Inverter-based Control to Enhance the Resiliency of a Distribution System
… maintain the voltage and frequency as done by synchronous machines, acting as the grid-forming inverter. This project focuses on the operation of grid forming sources based on the virtual synchronous generator to regulate the voltage and frequency in the absence of the grid voltage through …

Consensus-Based Active and Reactive Power Control and Management of Microgrids
… programming. For microgrids with distributed generators, seamless communication and secure operation are vital. This dissertation addresses the inclusion of noise as a constraint in grid-connected and islanded microgrids, aiming to enhance economic dispatch solutions and overall performance. A …

Compensating for the effects of reduced synchronous inertia on frequency stability using virtual synchronous generators
… grid has traditionally been dominated by large synchronous generators which have provided frequency stability through their inertia and governor responses. As more renewable energy sources (RES), particularly wind and solar, are added to the grid, they displace synchronous generators. Many of …

Decentralized optimization approach for power distribution network and microgrid controls
… tackle this problem, we introduce the concept of virtual inertia of DERs and cast the secondary frequency control design for isolated MGs as a consensus optimization problem. We solve it distributively by adopting the partial primal-dual (PPD) algorithm. Interestingly, parts of our specially …
