Voltage Instability Load Shedding

EPRI launched a supplement project titled "Coordinated Wide-Area Voltage Instability Load Shedding Helps Prevent Voltage Collapse". This project will develop a new hierarchical control architecture for coordinated wide-area voltage instability load shedding (VILS) using a combination of Voltage Instability Predictor (VIP) and Wide Area Measurement System (WAMS) concepts in order to help prevent voltage collapse and enhance the effectiveness of UVLS.

Probabilistic Reliability Assessment

The PRA program, developed by EPRI's Trans-mission Reliability Initiative, offers transmission companies a more accurate tool for assessing grid reliability under restructured market conditions. Unlike traditional deterministic analysis, PRA method takes into account both the probability of undesirable events and the severity or impact of the events.

Probabilistic Load Flow

There are many uncertainties in system planning area. Probabilistic Load Flow program models the uncertainties of generation and load and calculates the probability distribution function of line flows.  Performing PLF studies can help system planners identify the potential bottlenecks of transmission network and gain confidence when making investment decisions.

Transmission System Model Builder

Utilities, ISOs/RTOs and Regional Reliability Coordinators annually develops many power flow models. The process to collect, check, and merge the data to produce acceptable solved power flow base cases is complex and must be carried out in a careful and expert manner. EPRI is launching new supplemental project called ?Transmission System Model Builder?. The object of this project is to develop TSMB program to facilitate and expedite the model building process.

Load Modeling Phase 2 Update

Load Modeling Phase 2 launched in late 2005. In last few months, utility members focused on installing disturbance monitoring devices to collect disturbance data for load modeling purpose. A technical update on load modeling phase 2 will be given.
