| Means to reduce power losses in distribution systems include altering the network, placement of distributed generation, employment of low-losses transformers, short feeders and maintaining balanced loads. Distributed generation, when placed strategically, can reduce power losses improve voltage profile, load factors, reliability and efficiency. Reactive power is compensated by suitable shunt capacitor placements. Automated decision making without the influence of any manual operator at the load end to control the demand along with two way communication comes under distribution automation. Distributed generation, shunt capacitors and distribution automation will further the penetration of renewables into existing power systems without any serious issues related to transmission and distribution. Application of leapfrogging algorithm for optimal placement, sizing and scheduling of distributed generation (DG) and shunt capacitors (SC) to improve voltage profile, reliability indices and decrease power losses is discussed. Elimination of the two challenges faced by the traditional radial distribution systems i.e. non-uniformity in distribution voltage and peak demand is the objective. This prioritizes the optimization of efficiency and reduction of the impact and duration of outages. For obtaining the appropriate results, IEEE 33 distribution feeder is considered as the test feeder. |
