Summary: In the near future, integrating distributed energy resources (DERs) to build a microgrid will be crucial. This paper reviews the studies on microgrid technologies, including the modeling and optimization methodologies of DERs, and system control approaches for DERs and microgrids. The findings suggest that considering multimodal indicators can enhance the reaction capability of communities and stakeholders. The cost of operating a microgrid in isolated mode is significantly higher compared to grid-connected mode.

Summary: In this study, a model is developed to determine the optimal selection and dispatch of Distributed Energy Resources (DER) in order to evaluate the feasibility of using hydrogen as an Energy Storage System (ESS) in a microgrid. The model is implemented using GAMS and applied in a hypothetical microgrid using load profiles and market data. The results show that the adoption of DER brings both economic and environmental benefits, but the high investment costs currently make the use of hydrogen in a microgrid infeasible. However, considering environmental costs and market prospects, the adoption of this technology becomes a good alternative, improving energy management and reducing the total annual cost of the microgrid by 14.1%.

Summary: This paper presents a modeling and simulation platform for electric distribution grids that estimates overall power demand during extreme weather conditions. The effectiveness of the platform is demonstrated through estimation of electricity demand during the winter storm Uri in 2021 and hypothetical scenarios involving distributed energy resources, weatherization, and load electrification. Integration of distributed solar PV and storage improves local energy utilization and reduces potential unmet energy demand.

Summary: In this paper, a novel multi-objective microgrids (MGs) formation method based on network graph theory is proposed to minimize total losses, amount of load-shedding, and total restoration cost while ensuring various constraints. The model utilizes DRERs technology including diesel generators, fuel cells, micro-turbines, and renewables wind and PV units with energy storage systems, and non-linear equations for power flow and loss calculations. The effectiveness of the proposed approach is validated through case studies on single-fault and multiple faults, showing its impact on minimizing system losses, load-shedding, restoration cost, and improving system resiliency after natural disasters. The analytic hierarchy process (AHP) model is also applied to determine the most efficient operation scenario while considering the system objectives and alternative solutions.

Summary: This paper proposes a strategy for managing wildfire risks and preventing blackouts using microgrids, and demonstrates its effectiveness with a case study of the power network in Victoria, Australia in December 2019. By applying the Fire Weather Index (FWI) to a Wildfire-Energy System, the research provides a higher resolution for identifying wildfire risks in a grid. The results show that a system with installed microgrids can operate without outages under severe fire-related conditions. Additionally, a cost-benefit analysis indicates that networked microgrid solutions can recover 68% of system costs.

Summary: Climate change increases the risk of multiple extreme weather events, posing challenges for distribution system planners in a renewable energy era. This research proposes a resilience-oriented planning approach that considers various extreme events. A hybrid-stochastic-and-robust optimization model is developed to make flexible and affordable decisions, considering both long-term and short-term uncertainties. Case studies highlight the benefits of this approach in protecting distribution systems against multiple extreme weather events.

Summary: A new method has been developed to minimize the operating cost in microgrids integrated with renewables and energy storage systems (ESSs) through demand response. By shifting some of the load from high-price periods to low-price periods, the operating cost is reduced for operators and bill prices decrease for consumers. The optimization problem is solved using mixed integer quadratically constrained programming (MIQCP) in the General Algebraic Modeling System (GAMS) with the CPLEX solver.

Summary: Climate change increases the risk of multiple extreme weather events in a region, posing challenges for distribution system planners. Flexible planning approaches are needed to adapt to uncertainties in extreme weather scenarios. This study proposes a resilience-oriented distribution system planning approach considering multiple extreme weather events, using a multi-stage hybrid-stochastic-and-robust formulation. A progressive hedging algorithm embedded with a nested column-and-constraint generation method is developed to solve the model. Case studies demonstrate the benefits of the proposed approach in making flexible and affordable planning decisions to protect distribution systems against multiple extreme weather events.

Summary: Several remote communities with limited electricity access are being addressed by the installation of microgrid networks and green energy initiatives, with a proposed techno-economic assessment of a PV/hydro/diesel microgrid model. The results show that investing in a PV/hydro/diesel microgrid is the best economic option, with a net present cost of 2.33 M$ and a cost of energy of 0.194 $ kWh(-1). Additionally, a sensitivity analysis based on three different projected diesel prices was conducted to address diesel price uncertainties.

Summary: This article proposes a proactive generation redispatch strategy to enhance the operational resilience of power grids during hurricanes by minimizing load curtailments and operational costs. The strategy considers the unavailability and forced outages of renewable energy sources, as well as various constraints such as generation, transmission, and system limitations. The results show that the proactive and dynamic generation redispatch can significantly reduce load curtailments and improve power system resilience during hurricanes.
