Integrated System Model (ISM):

• ISM includes every piece of equipment in the system and every customer served by the system;
• Understand your customer load characteristics, forming customer classes based on statistical load analysis;
• ISM enables shared model use across the organization, supporting Design, Planning, Operations, Control, Maintenance, and Finance groups.
• Provides a consistent view, enhanced communication, and straight forward solutions to problems that are difficult or otherwise impossible to solve;
• Any data or calculation can be attached to an ISM model;
• When emergent problems arise, an ISM model improves the typical industry response (90% data gathering / 10% analysis) to basically 100% analysis;

Manage Costs, Revenue, and Reliability:

• Utilizing the DEW model can reduce capital improvement and operating costs, helping insure investments produce the anticipated results;
• Simulate before investing - a DEW case study evaluated two designs that provided similar safety & reliability, but had a 100 million dollar cost difference;
• Use load statistics to better size all equipment, as utilities have seen from 25% to 300% improvement in equipment sizing estimates;
• DEW allows you to evaluate revenue flows (by customer class) simultaneously with power flows;
• DEW can be used to design a consistent level of reliability based on local situations, rather than a global solution failing to account for local conditions;
• Develop plans for revenue growth, including systems that involve multiple energy supply sources including electric, steam, and gas systems.

 

Reduce Losses / Improve Efficiencies:

• Evaluate alternate system configurations to minimize losses;
• DEW can automate phase balancing of circuits to minimize losses and fully utilize available capacity;
• Use the DEW Phase Prediction application when existing phase connections are unknown, start balancing every new load that is added to system;
• Coordinate planning and operation of capacitors, voltage regulators, and distributed generation to minimize losses;
• Use integrated or coordinated control to optimize operating efficiency of distribution system;
• Avoid or delay building more costly substations by smart application of distributed generation;
• Design system to operate efficiently and reliably over the time varying load pattern, not just peak conditions;

 

Minimize Outages:

• Use Fault Analysis to predict location of fault occurrence, based on SCADA and AMI data.
• Use Switching Analysis to simulate switching plan and minimize impact of planned and forced outages;
• Use Reconfiguration application to reduce planning and response times during emergency or outage situations;
• Use Reconfiguration application to determine optimal reconfiguration of network during restoration, balancing loads between sources and equipment.
• Model storm types and outages from historical storm and outage data in the DEW model;
• Use storm models to predict outages and crews needed for developing storms;
