Products and Services (Monitoring and Analysis)

Ancillary Services Opportunity Cost (ASOC)


Generating companies in an energy/ancillary service market have the option to provide ancillary services (particularly load following, regulation, and contingency reserve) when they believe that their costs will offset by ancillary-service relevant revenue categories. These costs have many drivers, from the wear and tear on the units caused by following regulation signals to energy opportunity cost. The ASOC package was created to estimate how much ancillary services really cost and how well the market compensates their provision. The package helps analyze, pinpoint, and describe the causes of such costs. By collecting every few seconds the real-time operational data visible to operators and relating it to settlement results in detailed reports and easy-to-understand charts, ASOC provides a powerful platform for companies seeking to maximize the profitability of their operation in real-time markets.

Generation Control Display (GCD)

PCE has made available to PGC clients an innovative real-time display application for monitoring generation control performance and near-term future trends. The Generation Control Display (GCD) offers operators and managers a unique view of system performance data. It provides important information about the status of the system and is particularly useful in analyzing the performance of generation control and enhancing real-time decision making.

Generation Performance Monitoring (GenPM)

GenPM is an innovative system for the collection, storage, and presentation of generation control process data. It allows any user on the network to examine graphically and numerically, with user-friendly and presentation-ready plots, operational data for each individual unit as well as the entire system. GenPM allows analysts to get a picture of performance over a week or break down a specific minute of operation. It brings together real-time data, sampled and stored at intervals of a few seconds without loss of accuracy, with detailed market information and settlement data. GenPM provides the most comprehensive and powerful tool for finding and communicating opportunities for improving the generation control process.

Regulation Score Card (RSC)


The RSC package retrieves and stores all relevant data that affects regulation at the unit level. It then uses these values to calculate a number of performance statistics, including a PCE-developed index. This index measures the quality of a unit response to controls issued by AGC or PGC over periods of continuous regulation. The package provides statistics on this index and other parameters over any targeted time interval, including hourly, daily and monthly reports for each unit or the entire system. RSC has been used to promote more responsive plant regulation performance and to identify problems in plants in order to create a more reliable and economically efficient system.

Visual Economic Dispatch (VED)


Based on technology utilized in PCE's state-of-the-art Priority-based Generation Control system, this tool will help in both real-time and predictive analysis of the optimum distribution of generation. Visual Economic Dispatch enables operations staff to quickly run an economic dispatch analysis of multiple current and future scenarios, and identify actions that will help improve overall efficiency of production.
