MicrogridsGrid-scale capabilities for localized energy

With dynamic energy storage control software, microgrids can take on a high penetration of renewables while optimizing various generation sources and energy storage systems to provide the most cost-effective power source and providing stable and reliable energy to the grid.

Benefits

Maintain Stability & ReliabilityMicrogrids are complex distributed energy systems that feature local generation and storage to inter-connected loads. They present a unique set of challenges for grid owners and operators. These electrically islanded systems can operate with or without a connection to the grid. The ability to operate independently assures reliability and resiliency for customers with critical power needs who cannot afford untimely service interruptions.

Upon delivery, our systems have a proven track record for safety and reliability for high-power applications such as frequency response and high energy functions like energy shifting. GEMS ensures maximum return on investment for microgrids while enabling optimal storage system design, integration, and operation.

Control High Renewable EnvironmentTraditional grid operators, without adequate energy storage capacity, follow conservative limits on the deployment of renewable energy resources to maintain reliability. With islanding capabilities, microgrids can safely lift all limits on renewable penetration, bringing a substantial benefit in places where electricity prices exceed the levelized cost of electricity of renewables - resulting in lower energy costs and a smaller carbon footprint.

Project Lifecycle Case Study

Heavy dependence on fossil fuel imports, and often isolated, puts islands around the globe in a very unique bind as it relates to energy security.

Upon completion, the Graciosa Hybrid Renewable Power Plant will enable 1 MW of solar - 4.5 MW of wind power and a 6 MW/3.2 MWh energy storage system to be supplied to the local grid, reducing the islands’ reliance on petroleum imports and increasing the reliability and stability of the grid.

Graciolica Lda anticipates this investment will boost renewable energy consumption from 15% to 65% once the plant is fully operational in late 2018 and eliminate the need for 17,000 liters of diesel per month.

PlanWe understand the evolving energy market and recognize value-based opportunities for our customers. We align business objectives with technical expertise through extensive modeling.

DeployOur parent company Wärtsilä is a leading engineering, procurement and construction (EPC) provider, and provides support for our energy storage and integration opportunities through our life cycle service solutions.

OptimizeOur GEMS software is tightly integrated with the battery management system (BMS) and power conversion system (PCS) - maximizing the life of the system. We also provide a comprehensive portfolio of services for your post-deployment needs.

GEMS for Microgrids

OptimizationGEMS optimization algorithm dynamically results in the lowest LCOE given the resources available. Forecast load and weather data allow GEMS to properly position engines to minimize run times and operate at highest possible efficiency resulting in fuel savings. GEMS connects to all generation sources to operate as island grid controller.

ImplementationImplementation of this operational algorithm requires:

• Command and control over all generation assets in the microgrid

• Detailed grid studies to understand operation of the grid in stress cases

• Detailed modeling of historical load and weather data to build basicoptimization algorithms
