Summary: With the exponential increase in the penetration rate of EVs, the charging load is causing new issues in the power system such as voltage drop. Improperly located EVCSs exacerbate these issues, leading to concentrated charging demand. This paper proposes a method for optimal EVCS placement considering installation cost, drivers' preferences, and existing charging stations. By estimating charging demands using kernel density estimation and modeling driver preferences, an integer nonlinear programming problem is formulated and solved using a minimax genetic algorithm. Simulations based on real data demonstrate the effectiveness of the proposed method in achieving dispersed charging demand.

Summary: Over the past decade, the integration of grid-edge inverter-based distributed energy resources (DERs) has grown rapidly, causing concerns about reduced system inertia, stability, and intermittent renewable power generation. However, smart inverters can provide grid services to maintain reliable grid and microgrid operations. Power hardware-in-the-loop (PHIL) is a strong testing solution that enables real-time simulation of power systems to determine interactions between multiple inverters at different points on the grid and microgrids. This paper reviews recent advancements in PHIL for grid and microgrid applications and proposes a research paradigm to advance the integration of smart grid-following and grid-forming inverters.
