Abstract / Description of output

Active Network Management schemes are being developed to accommodate larger volumes of renewable generation within distribution networks. Approaches typically manage only single technical constraints or are highly complex with extensive sensing and communications needs that bring cost, deployment, and operational risks. This work offers an alternative, decentralized approach for real-time management of local voltage and thermal constraints that avoids extensive sensing and communications. It controls generator active and reactive power output to overcome voltage and thermal issues near the point of connection. Results from time-series analyses reveal its effectiveness in managing both constraints and allowing greater production. It represents a potentially effective and fast-to-deploy alternative to more complex, integrated solutions.
