Grid operators: Wide grid monitoring using satellite time

Future Grid Operation ChallengesEnhanced Visualisation of Grid ConditionsEnhanced Automated Grid ControlGrid Operators Need A Thermostat, Not A ThermometerAbout The AuthorsToday, operating the grid is becoming even more challenging due to many new trends. These include: • Adverse weather patterns becoming increasingly severe; • Demand response programmes and customer engagement unpredictably changing load; • Distributed generation resources with energy outputs that are difficult to predict; • Electricity market systems resulting in more unpredictable electricity flows; • Generation company decisions that may be independent of the transmission company decisions; • Challenges in forecasting load, generation capacities and operating margins; and • Maximising utilisation of existing grid assets resulting in operation closer to equipment limits. Fortunately, new technologies and solutions are being developed to address these issues. Two such key solution domains are the focus of this article. They are enhanced visualisation of grid conditions and enhanced automated grid control.Get price
