Concorda MARS Engine
The Concorda MARS engine enables electric utility planners to quickly and accurately assess the ability of a power system, comprised of a number of interconnected areas, and to adequately satisfy the customer load requirements. Based on a full sequential Monte Carlo simulation, MARS performs a chronological hourly simulation of the system, comparing the hourly load demand in each area to the total available generation in the area, which has been adjusted to account for planned maintenance and randomly occurring forced outages. Areas with excess capacity will provide emergency assistance to deficient areas, subject to transfer limits between the areas.
Features & Benefits
- Widespread use and acceptance in North America
- Enables system planners to study impacts of variable generation on reliability
- Area and pool based calculation of standard reliability indices of daily and hourly LOLE (loss-of-load-expectation), and expected unserved energy
- Calculates time-correlated indices such as frequency and duration of outage
- Determines the expected number of days or hours per year that various emergency operating procedures would need to be implemented
