South Fork of Long Island (SFLI) is a high-density residential area facing power shortage in coming years. Due to large summer population, the electricity demand has a distinct seasonal pattern. The annual average power demand is 55 MW, however the summer month demand is 95 MW on average, reaching values as high as 140 MW for 10-20 hrs. In this project CIEES-UTS team is evaluating liquid salt (ZEBRA) batteries as an energy storage solution for South Fork region. ZEBRA batteries offer a low-cost energy storage that is better suited for an area with distinct seasonal energy demand. The battery normally operates at 300oC, when cooled to the ambient temperature it can be stored indefinitely. A battery farm would be activated for summer month only, thus requiring no off-season maintenance.

Principal Investigator: Dr. Yue Zhang
Industrial Partner: Sunrise Wind LLC and Orsted CorporationThis project addresses two of the most important challenges in offshore wind (OSW) energy integration into NYISO Zone K and I – onshore transmission upgrade and onshore grid stability – by developing comprehensive energy storage solutions.
(Left) Wind farm leases off the coast of Long Island. (Right) Rendering of the proposed wind farm off the Long Island coastOnshore grid transmission upgrade has been identified as the most challenging issue in OSW integration, not only for achieving the current OSW integration target but also even more so for the greater OSW goals in the long run. Existing studies on transmission upgrades in the NYISO territory have been simplified as wind energy forecast errors and system contingencies are ignored, whereas real-world power system operations in the presence of forecast errors and contingencies will encounter much more complex scenarios and potentially require a significantly higher need for transmission upgrade. In this project, the flexibility of energy storage will be exploited to absorb the OSW forecast errors and the system shocks due to contingencies and ultimately significantly reduce the need for transmission upgrade and the barrier to massive OSW integration in NYISO Zone K and I. The CIEES team investigates optimal energy storage placement, sizing, and operation strategies under realistic power system operation settings with massive OSW, and evaluates the value of storage in reducing the need for transmission upgrade and OSW curtailment. Another challenging issue with massive OSW is grid stability in the presence of a) rapid fluctuations of wind energy and b) reduced system inertia as fewer conventional synchronous generators are present. The team utilizes the fast control of energy storage, inverters and OSW wind turbines for stabilizing the voltage and frequency of the onshore grid. The deliverable is a hi-fidelity dynamic model and simulator of the Zone K and I with OSW and storage, and comprehensively evaluates the benefit of storage control in improving the onshore grid stability.

Industrial Partner: Bren-Tronics, Inc.Long Island (LI) is a high-density residential area where a large number of renewable energy generation systems have been installed or are at the planning stage. Several Eastern LI load pockets: South Hampton, East Hampton and Montauk are facing summer power shortages due a high seasonal demand. For example, the average annual demand of the South Hampton load pocket is 55 MW, however the summer months can be as high as 140 MW for 10-20 hrs. Behind-the-meter energy storage, which we believe does not require a lengthy and expensive permitting process, can be rapidly deployed and help alleviate this demand with renewables.
BrenTronics and the CIEES team developed a behind-the-meter energy storage solution by redesigning an existing 5 kWh, 48 V battery, currently offered by Bren-Tronics to DoD customers. The unit complies with rigid MIL-Spec safety standards, thus this solution is a good fit for residential behind-the-meter, on-premises installation where fire, flood and electrical safety are very important. The flood safety is especially relevant for neighborhoods in flood-prone coastal areas, such as the South Shore of LI (as witnessed during SuperStorm Sandy). The market opportunity is estimated at $20M annually, the main source of revenue being the installation and service of the battery storage systems.

Application of high-volume supercapacitor in microgridPrinciple Investigator: Dr. Benjamin Hsiao
Funding Agency: US Navy Office of Naval ResearchRemote military bases or communities can have a wide range of systems, spanning from the kW to GW, with different complexity and maturity. There is a lack of integrated "plug-and-play" mobile energy storage solutions that can be seamlessly integrated into a microgrid without compromising the grid power quality.
The popular microgrid management approach is droop control-based; the strategy inherited from the traditional electric grid, where stability is ensured by multiple synchronous generators operating at a 4-5% frequency droop. Absent inertia of large generators in an islanded microgrid requires intermediate energy storage systems to absorb or inject power through pre-determined or adaptably adjusted droop curves. However, under large load variations, such as shipboard electromagnetic weapon platforms and high-power electric vehicle chargers on forward bases, droop controllers are known to demonstrate poor damping performance.
Layout of the microgrid prototype. The arrows show dispatch communications. The left panel shows the BRENERGY 4850 Li-ion battery used in this study.The project uses a communication-based multi-agent approach using secure wired communication, CAN and RS-485. By inter-connecting the loads and generators within the microgrid, optimal energy dispatch can be realized through a look-ahead load prediction strategy. Under this scenario, a load controller will communicate the anticipated energy dispatch to the distributed energy resource (DER) and the energy storage unit. Here we use the most advanced in the internet of things (IoT) communication to demonstrate predictive energy dispatch of a Mil-spec energy storage (Bren-Tronics BRENERGY TM 4850 Li-ion storage), commercial out-of-shelf (COTS) inverter, under a variety of loads. The proposal team fully utilizes synergy between SBU's expertise in wireless communication and Bren-Tronics experience in supporting US warfighters with state-of-the-art energy solutions.

Funding Agency: National Science FoundationThe main objective of this project is to create smart programmable microgrids (SPMs). Our key innovation is to virtualize microgrid functions, making them software-defined and hardware-independent, so that converting distributed energy resources (DERs)to community microgrids becomes affordable, autonomic, and secure. To achieve our main objective, our team will: 1) Architect a programmable microgrid platform for virtualizing traditionally hardware-dependent microgrid functions as flexible software services, fully resolving hardware dependence issues and enabling unprecedented low costs; 2) Pioneer a concept of software-defined operation optimization for microgrids, where operation objectives, grid connection, and DER participations will be defined by software and plug-and-play, and can be quickly reconfigured, based on the development of modularized and tightened models and a novel asynchronous price-based decomposition-and-coordination method; 3) Devise a software-defined distributed formal analysis for online stability assessment under heterogeneous uncertainties and plug-and-play of microgrid components or microgrids; 4) Develop a real-time-learning-based cybersecurity function to protect SPMs against power bot attacks; and 5) Enable anaerobic-biomass-digesters (ADs) as environmentally friendly and dispatchable DERs by virtualizing the dispatch and control of ADs in SPM. The proposed SPM will be demonstrated on a Connecticut community microgrid through a recently built cyber-physical testbed.
