The Maxwell Grid Cell Pack is based on utility requirement-driven design expertise, with a critical eye on power system integration at the microgrid level and also for behind-the-meter C&I applications. Maxwell works directly with global utility equipment OEMs and your preferred suppliers to deliver optimized solutions based on specific technical project needs that are higher performance and lower cost than stand-alone battery energy storage.
Maxwell Advanced Modeling and Simulation
Maxwell offers industry leading lifetime prediction capability with our advanced ultracapacitor cell lifetime estimation tools based on over 3 million hours of product testing. With this foundation, Maxwell’s grid solutions team works hand-in-hand with stakeholders and uses state-of-the-art tools to model system dynamics when integrated in the power grid with traditional and renewable generation resources along with grid control systems. This provides the technical justification, financial justification and deep analysis required by the utility, project developers, ratepayers and appropriate regulatory and governmental bodies.
Solar and wind power firming
Mitigate msec-sec timeframe power fluctuations to ensure local power quality, especially on long feeders or with a high penetration of renewable energy. Enable interconnection of more renewable projects which would otherwise require costly infrastructure investment.
Maxwell ultracapacitors are deployed as a stand-alone asset or integrated with batteries to provide near real time frequency, voltage and power firming and smoothing in island mode. These devices meet the most demanding transient and pulsed power loads and provide the highest level of availability and reliability in support of utility microgrids, commercial and industrial microgrids, campuses and industrial parks, and critical assets including defense and military microgrids.
Voltage sag mitigation and UPS
In utility grids and microgrids, Maxwell ultracapacitors provide voltage, frequency and power stabilization in near real time. Fast responding, transient response capability mitigates deep and/or recurring power sags from cycles to minutes. In manufacturing and C&I facilities, ensure delivered power meets ANSI, CBEMA and SEMI standards for continuous operations and to mitigate risk of financial loss. Systems can be sited on utility side or customer side-of-meter and occupy a significantly smaller footprint providing faster response than alternative battery and generator solutions.
Primary frequency response
Renewables do not provide the necessary inertia and short circuit power to the power system. Maxwell ultracapacitors provide fast frequency response (FFR) as a stand-alone system or integrated with batteries. Fast, reliable cycles timeframe response for synthetic inertia can also be provided when integrating with SVC, STATCOM or as a replacement to SYNCON. Enable interconnection of assets such as PV and wind, stabilize voltage and frequency while replacing the system inertia deficit due to retired fossil and nuclear generation plants. Fast response to mitigate, in near real time, a decrease in generation, generation-load imbalance and unpredictable variations in demand.
Generator bridging, ramping and regulation
Maxwell ultracapacitors provide controlled ramp rates from cycles-to-seconds-to-minutes until generator ramp is complete. Reduce the need for idling resources and reduce fuel consumption. Fast responding energy storage to respond to an increase or decrease in generation (or load), to respond to markets or random, unpredictable variations in demand.
Rail to utility – Wayside rail energy recovery
Provide assisted propulsion, bridge power, and grid/voltage stabilization.
Hybrid storage – Asset optimization and stacked services
New levels of stacked functionality are now achieved by integrating traditional Li-ion and other battery chemistries with ultracapacitors. Capacity, peak load management, energy arbitrage, near real time voltage and frequency stabilization and regulation, FFR (fast frequency response), synthetic inertia, bridging and ramping can be combined in one system to maximize asset use, increase benefit-to-cost ratio and decrease payback period.
