Optimum under-frequency load shedding with comparison of two load models for distribution system

The distribution system connects customers to the rest of electrical grid. network suffers from rising power losses and low frequency, which are greater than transmission voltage problems. One solutions for these problems furnished by under-frequency load shedding based on optimal selection loads using a suitable optimization algorithm. Because its simple design inexpensive cost, radial (RDS) was chosen. Two models (constant model ZIP model) implemented with comparisons between them. A Gravitational binary search algorithm is used purpose accurate results, made demonstrate efficiency proposed method. BGSA useful in order reduce space minimum be shed location. IEEE 33-bus employed check validity suggested attitudes. Direct Backward Forward Sweep Method (DBFSM) show total each node as it represents flow method RDS. results ability provided methodologies find best solution large loss reduction better profile
