Reactive support allocation using improved Y-bus matrix method

摘要: In deregulated power systems ancillary services including reactive supply are unbundled for transparency and accurate cost identification. Sufficient is essential secure operation of systems. Reactive supplied by generation-based static sources used two purposes: direct consumption at loads system-wide voltage management. The task the system operator to identify which part any source who consumes this. Accordingly, revenue collected from consumers distributed among providers. Therefore an appropriate transparent pricing scheme will encourage more generators participate in market, increasing stability because increased availability. However, existing allocation methods do not always provide unquestionable results. proposed circuit theory-based method identifies different allocates amount provided using improved Y-bus technique along with proportional or equal sharing principle. Line charging reactance present transmission line supplies system, identified as a separate first time this study method, offers supplying means reactance. By doing so, eliminates some important drawbacks methods. tested on IEEE also 400 KV practical system.
