Multi Area Reliability Simulation (MARS) modeling software
MARS, our reliability assessment software, provides detailed system resource adequacy assessments to inform grid planners.
Assess system adequacy with Monte Carlo simulations
The Multi-Area Reliability Simulation (MARS) engine enables electric utility planners to more quickly and accurately assess the ability of a power system, comprised of a number of interconnected areas, to help adequately satisfy 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. This reliability analysis software will analyze the areas with excess capacity and will provide emergency assistance to deficient areas, subject to transfer limits between the areas.

MARS software applications
1
Conduct probabilistic power and reliability assessments of generation capacity adequacy, such as NERC PROB-A, to ensure system reliability and potential risks.
2
More accurately assess the impact of variable renewable generation, additional transmission lines, and energy storage.
3
Perform calculations such as equivalent load carrying capacity to better meet resource adequacy demands.
4
Assess reliability of power supply in meeting energy demand.
5
Determine the need for implementing emergency operating procedures down to hours/year to help avoid system failures.
An inside look at MARS
How the MARS API and GUI streamline your project workflow
MARS comes with a user interface (GUI) and Python application programming interface (API) that greatly improve the user experience.
The UI provides several features including:
- Easy-to-use, structured file handling for all your cases
- Special-designed text editor with documentation to make input table handling easier
- Create and save input and output tables using .csv and .xlsx formats.
- Intuitive calculation management
- Professional-quality report creation
The API allows Python users even more power, including:
- Automated postprocessing calculations and report generation
- Prepare and run calculations on a local or remote computer.
- Create inputs from any data source that can be handled in Python.
- Planning the energy transition with Consulting Services software
- Planning software for the energy transition
- Planning for uncertainty: the value of stochastics
