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.
Optimal DER Selection and Sizing
XENDEE quickly identifies the optimal DER portfolio for custom-built, site-specific projects. Design microgrids that are resilient and low-cost, without the hassle of repeating dozens of analyses with different DER combinations. The user indicates the range of technologies that are being considered for the project, and XENDEE pinpoints which technologies will provide the technically and economically optimal solution. The interplay between the technical and economic characteristics of DERs, as well as the hourly dispatch optimization, determines the best mix of technologies to meet the needs of the project without unnecessary oversizing.
Custom, Optimized DER Portfolios
Least-cost solutions for increased resilience
Lower emissions and meet regulatory standards
Tailored, site-specific analysis to maximize return on DER investments
Optimal DER Siting Considering Power Flow and Heat Transfer
Through seamless integration with our Power Systems modeling tool, microgrid configuration uses power flow models to optimize technology siting for multiple units. Optimal placement and dispatch reduce losses, resulting in a solution that incorporates least cost operation of on-site technologies. Create the microgrid topology using the one-line diagram building tool. Seamless integration between the power flow analysis feature and the optimization feature automatically updates your microgrid design optimization project with cable and transformer data and facilitates swift analysis for multinode microgrid configurations.
Distinct Energy Domains
For complete accuracy in modeling energy domains, XENDEE characterizes loads as multiple end-uses. XENDEE identifies opportunities for increased efficiency and reduced costs through heat recovery with a comprehensive approach to thermal technologies. Thermal loads can be met by a complete host of sources, including CHP-enabled discrete technologies. Losses are fully accounted for, and Electric Vehicles are considered as a source of electricity storage and dispatch. This modeling is based on the Distributed Energy Resources Customer Adoption Model (DER-CAM) from Lawrence Berkeley National Laboratory. BankableEnergy | XENDEE is the only industrial provider of DER-CAM, which offers support and integration of techno-economic optimization, power flow, and project management capabilities in one single software platform.
XENDEE considers more value streams through microgrid adoption than any other modeling software. Through consideration of opportunities for increasing efficiency, increasing reliability and resiliency, and reducing utility, operations, and maintenance costs, XENDEE designs microgrids that are configured to take advantage of all possible avenues to cost reduction.
Demand Charge Reduction
Energy Charge Reduction
Reduction in Lost Energy through Microgrid Configuration
XENDEE’s advanced energy management modeling incorporates load shifting and demand response into the value stream calculations. The resiliency modeling optimizes the mini-grid for fight-through capability at minimum costs. While other providers decouple the decision-making for technology sizing from the outage modeling, XENDEE incorporates both into the optimizer, thereby ensuring that resiliency is a key variable in microgrid configuration. Optimal solutions are simultaneously driven by resiliency and cost factors, keeping the lights on and keeping the costs low.
