In the modern electric power grid, distributed energy resources (DERs), such as rooftop solar, small wind, and**energy storage, are expected to gradually displace conventional centralized fossil fuel-based generation. While**DERs (specifically renewable generation) may pose numerous challenges for reliable and efficient grid**operations, they offer more flexible capabilities to support and optimize the integrated power system from the**customer side. Through this Engage Grant, we will design control strategies to optimize and regulate DER**output voltages in real time, while ensuring that the system remains within operational constraints enforced by**the electric utility. The proposed work will be conducted in collaboration with Enbala Power Networks Inc.,**which develops innovative algorithmic and software solutions that manage and optimize the performance of**the modern power grid.**Large voltage excursions, primarily arising from rapidly varying renewable generation, will challenge reliable**and efficient operation of the future distribution grid. In recent literature, the so-called voltage-droop control**method has been shown to be a promising strategy to regulate DER output voltages. We will design optimal**voltage-droop characteristics and update them adaptively as the system operating point changes over time.**Additionally, in order to facilitate practical interoperability between DERs from various manufacturers and the**electric grid, the developed controller will comply with existing industry standards for control and**communication protocols. By leveraging flexible capabilities of DERs, the project outcomes will help to**ensure power availability and quality while enabling greater renewable penetration and customer participation.
