Optimal Microgrid Solutions for Complex Power Distribution Networks - Case Study of Clarkson Ave. Microgrid Distributed Energy Resources (DERs) Selection, Sizing, and Optimization


Microgrids are being developed and implemented to support modern electrical grids and to increase power resiliency, lower operating costs, and to improve environmental sustainability. There are many different DER technology options and operating strategies to assess when attempting to optimize microgrid technical and economic performance. Variables include but are not limited to site conditions, thermal and electric load patterns, rates and tariffs, environmental restrictions, fuel costs and electric market programs. Clarkson Avenue Microgrid is investigated for DER selection and optimization using the Distributed Energy Resources-Customer Adoption Model (DER-CAM) software developed by Lawrence Berkeley National Laboratory (LBNL).

Clarkson Avenue Microgrid has been awarded as New York Prize Microgrid project. This potential 18MW microgrid would provide power to three critical adjacent healthcare campuses in central Brooklyn — Kingsboro Psychiatric Center, Downstate Medical Center, and Kings County Hospital Center. The microgrid is expected to consist of existing assets (5.3MW of fuel cells and 1.6MW of CHP) plus new solar PV, natural gas generators, and battery energy storage. All DERs will be able to be operate in parallel with the utility and also in disconnected island-mode during grid outages.

Cases are investigated and it is demonstrated how and to what magnitude different objectives and constraints impact DER selection and operation, and how the DER-CAM optimization tool guides DER selection and microgrid design.
