#CYME TIME WANKSTAR VERIFICATION#
The verification of power and energy availability for the operation of islanded microgrids at peak and during extended periods. The identification of under- and over-voltage conditions and overloads under multiple scenarios. This unique combination of detailed system modeling and refined steady-state analyses facilitates the design, planning and operation of microgrids, allowing for instance: A customizable load shedding and curtailing algorithm embedded into the power flow solver for islanded simulations where the load offsets the available generation. The ability to perform unbalanced power flows, short circuit analyses and time-series simulations on islanded and grid-connected microgrids. The detailed modeling of grid-forming DERs, such as isochronous and droop control modes, considering their operational and/or physical limits. Simply put, the module lifts the simulation requirement for a source equivalent to exist in any connectivity model. The CYME Microgrid Modeling and Analysis module enables the modeling and simulation of grid-tied microgrids operating in either islanded or grid-connected mode as well as isolated microgrids, such as those of remote communities far from any transmission and distribution infrastructure. IEEE Standard for the Specification of Microgrid Controllers," in IEEE Std 2030.7-2017, vol., no., pp.1-43, 23 April 2018 The IEEE Standard for the Specification of Microgrid Controllers (IEEE STD 2030.7™ ) defines a microgrid as "a group of interconnected loads and distributed energy resources with clearly defined electrical boundaries that acts as a single controllable entity with respect to the grid and can connect and disconnect from the grid to enable it to operate in both grid-connected or island modes." The implementation of microgrids can yield several benefits to electric utilities and their customers: improved grid reliability and resilience, loss reduction and cost savings, decreased grid congestion, capital infrastructure deferral, etc. The CYME Microgrid Modeling and Analysis module is part of this trend and enables unprecedented simulations of islanded - but also grid-tied - microgrids. 
Often referred to as non-wires alternatives (NWA), this new class of solutions leverages modern technology to mitigate grid risks without resorting to traditional capital expenditures. The rise of distributed generation and, in a broader sense, of distributed energy resources (DER) challenges electric utilities, but also creates a new space for engineers to design innovative solutions to improve grid performance.
