Optimal sitting and sizing of Distributed Generation

Matlab is one the important programming stream and consider as hottest research area now a day's, this area has very vast application in real world. Efficient methods and technologies are highly required to this world to reduce the calculations and perform the operation in precise manner. The power system is very abstruse subject so there is a need of optimum solutions with which the system becomes optimized and economical by solving complex problem. There are many benefits to install a DG in system but the problem is there is need to do complex calculation to know the size and the placement of DG. Benefits of employing DG are analysed using Voltage Profile Improvement Index (VPII) and Line Loss Reduction Index (LLRI). The optimal size and location of DG for a distributed system is the basic purpose of this paper.
