Optimal DER Dispatch and Microgrid Configuration

XENDEE is the best Microgrid modeling tool to optimize the hourly dispatch of all energy sources, as well as the possibilities for load shifting, demand response, and curtailment.

The interplay between optimal sizing and optimal dispatch is often disregarded in modeling tools. XENDEE simultaneously determines an optimal DER portfolio and optimal dispatch schedules by including hourly dispatch as a key decision variable, capturing crucial interactions between parameters such as technology efficiencies, fuel prices, utility rates, charging and discharging rates, and irradiance profiles that are missed by rule-based approaches to technology dispatch.

Optimizing hourly dispatch identifies the best opportunities for demand charge and energy charge reduction. The automatically generated dispatch curves help users see how the interactions between technologies and the utility bring the most benefit to the client.
