The distribution system configuration can be modified using line switches. This approach enables the loading of line segments and distribution feeders to be adjusted to obtain the load balance and enhance the system performance due to loss minimization resulting from the presented generic switching actions. This paper develops the optimal switching actions for the 22.8 KV underground distribution...
A significant portion of electric utility operating expense comes from the energy production. In order to minimize the cost, unit commitment (UC) scheduling is an important tool to properly assign generation units to accommodate the forecasted system demand. The short-term load forecast is a prerequisite for UC planning. The projected load up to 7 days ahead is important for the reconfiguration of...
The benefits in performance (sensitivity and speed), reliability (security, selectivity, and dependability), availability, efficiency, economics, safety, compatibility, and capabilities of microprocessor multifunction protective relaying (MMPR) technology over the previous existing technologies, namely electromechanical and solid-state, are explored. The suggested typical values, quality measurements,...
The reliability of the electrical power system supply requests often set up more sources. For a good design, a proper installation and operation, all the admissible sources sets and the related operating procedures have to be defined, including contingency conditions. The studies of the integrity procedures have to consider load flow and short circuits analysis . The clear evaluation of all the sources...
