==Load flow calculation==

The load-flow calculation<ref>{{Cite journal|last=J. Arockiya|first=Xavier Prabhu|year=2016|title=Design of electrical system based on load flow analysis using ETAP for IEC projects|journal=Power Systems (ICPS)|volume=|pages=1–6|doi=10.1109/ICPES.2016.7584103|isbn=978-1-5090-0128-6}}</ref> is the most common network analysis tool for examining the undisturbed and disturbed network within the scope of operational and strategic planning.

Using network topology, transmission line parameters, transformer parameters, generator ___location and limits, and load ___location and compensation, the load-flow calculation can provide voltage magnitudes and angles for all nodes and loading of network components, such as cables and transformers. With this information, compliance to operating limitations such as those stipulated by voltage ranges and maximum loads, can be examined. This is, for example, important for determining the transmission capacity of underground cables, where the influence of cable bundling on the load capability of each cable has to be taken also into account.

[[General Electric]]'s MAPS (Multi-Area Production Simulation) is a production simulation model used by various [[Regional transmission organization (North America)|Regional Transmission Organizations]] and [[Independent System Operator]]s in the United States to plan for the economic impact of proposed electric transmission and generation facilities in FERC-regulated electric wholesale markets.<ref>{{cite web|title=GE Multi-Area Production Simulation|url=https://www.geenergyconsulting.com/practice-area/software-products/maps|work=www.geenergyconsulting.com|accessdateaccess-date=November 26, 2018}}</ref><ref>{{cite web|title=GE Multi-Area Reliability Simulation|url=https://www.geenergyconsulting.com/practice-area/software-products/mars|work=www.geenergyconsulting.com|accessdateaccess-date=November 26, 2018}}</ref><ref>{{cite web|title=GE Power System Load Flow Simulation|url=https://www.geenergyconsulting.com/practice-area/software-products/pslf|work=www.geenergyconsulting.com|accessdateaccess-date=November 26, 2018}}</ref><ref>{{cite web|title=NYSRC 2018 IRM Study Report|url=http://www.nysrc.org/pdf/Reports/2018%20IRM%20Study%20Report%20Final%2012-8-17[2098].pdf|p=2|work=www.nysrc.org|date=December 8, 2017|accessdateaccess-date=November 26, 2018}}{{Dead link|date=May 2020 |bot=InternetArchiveBot |fix-attempted=yes }}</ref><ref>{{cite web|title=NYISO Notice to Stakeholders of Request for MAPS data|url=https://www.nyiso.com/public/webdocs/markets_operations/documents/Legal_and_Regulatory/Notices/MP_Notices/Notice%20to%20Generators%20re%20GE%20MAPS%20database%20input%20files%20for%20CARIS%202%20-%209-9-14.pdf|work=www.nyiso.com|date=August 2000|accessdateaccess-date=November 26, 2018}}</ref>

Portions of the model may also be used for the commitment and dispatch phase (updated on 5 minute intervals) in operation of wholesale electric markets for RTO and ISO regions.

[[ABB]]'s PROMOD is a similar software package.<ref>{{cite web|title=ABB PROMOD Market Simulation|url=https://new.abb.com/enterprise-software/energy-portfolio-management/market-analysis/promod|work=new.abb.com|accessdateaccess-date=November 26, 2018}}</ref>

These ISO and RTO regions also utilize a GE software package called MARS (Multi-Area Reliability Simulation) to ensure the power system meets reliability criteria (a loss-of-load-expectation (LOLE) of no greater than 0.1 days per year). Further, a GE software package called PSLF (Positive Sequence Load Flow), a [[Siemens]] software package called PSSE (Power System Simulation for Engineering) and [[Electrical Transient Analyzer Program]] (ETAP) by Operation Technology Inc.<ref>[https://etap.com Operation Technology Inc.]</ref> analyzes load flow on the power system for short-circuits and stability during preliminary planning studies by RTOs and ISOs.<ref>{{cite web|title=Siemens PSSE|url=https://www.siemens.com/global/en/home/products/energy/services/transmission-distribution-smart-grid/consulting-and-planning/pss-software/pss-e.html|work=www.siemens.com|accessdateaccess-date=November 26, 2018}}</ref><ref>{{cite web|title=New York State Resource Planning Analysis (NYSPSC)|url=https://www.nyiso.com/public/webdocs/markets_operations/committees/mc/meeting_materials/2015-12-17/Agenda%2004_NYSDPS%20SRP%20Presentation_revised.pdf|work=www.nyiso.com|date=December 17, 2015|accessdateaccess-date=November 26, 2018}}</ref>
