The unique characteristics that make microgrids so attractive-including their ability to power critical facilities, enhance community resilience and integrate clean energy resources-are the same characteristics that often leave them in a regulatory grey space.
However, microgrids often face a variety of financial and regulatory barriers that limit their deployment. It’s a suite of technologies designed around a pragmatic admission: that the power grid is vulnerable and will at times fail. These unique systems represent a specific form of electric resilience-the ability to maintain power locally even in the face of wider system failures. In 2021 alone, there were 20 separate “billion-dollar disasters,” causing total losses of nearly $150 billion.Īs state lawmakers consider policies to enhance energy system reliability and resilience, a growing number have looked to the benefits of microgrids.
The previous decade was far and away the most destructive since the federal government began tracking these storms in 1980-both in terms of the frequency of severe storms and their destruction. The threat from natural disasters has grown in intensity and frequency. The electric grid is considered especially important because power is required to maintain the functionality of most critical infrastructure sectors-those deemed vital to the economy, public health and safety. The United States faces a growing threat from natural disasters and energy infrastructure is in the eye of the storm.

The study presents a comparative assessment of the response of RC-droop and conventional droop in the varied microgrid conditions. This is essential for the operation of critical loads. The networked control systems aids in achieving proper load current sharing and desired voltage regulation. The grid-feeding converters, both voltage and current-controlled, are interconnected via communication layer and are governed by the consensus laws for multi-agent systems. The converters considered are both grid-feeding and grid-forming in order to analyze the response in the presence of dissimilar electrical energy sources. A RC-based droop control strategy is employed in this work in order to impart inertia to the system thereby improving the transient performance of the network. Since in large distribution networks, lack of inertia is the cause of instability, virtual impedance based methods and capacitor control techniques have been proposed. It employs a generalized DC distribution network consisting of both current-controlled and voltage-controlled voltage source converters and a mix of constant impedance, constant current and constant power loads. This paper investigates the performance assessment of droop controlled converters in a low inertia, low voltage DC microgrid scenario.
