SOlar Grid Integration Issues:Over Voltage Dilemma

日期 : Jan 2016 - Jan 2017

In this modern era of technology where, electricity is the life line for human needs. There exists two main approaches for electricity namely conventional and non-conventional. Despite of unfriendly behavior of conventional power plants (CPP), almost 77 percent of global electricity (GE) being generated by CPP and unfortunately only 23 percent of GE is generated by most environmental friendly way, non-conventional power plants (NCPP). No doubt that the world is now seriously looking for NCPP to generate electricity to reduce the impact on environment and to ensure safe energy with reliability but there required lot of study before its full functionality. From the many sources of NCPP, the Solar Power is one of the major source of electricity in the world. This paper is based on the study of the one of the major issue “overvoltage protection scheme” which is occur when solar power is added at a power grid. To illustrate this issue a well-known electrical software named “Electrical Transient Analysis Program” is used. This study is based on the simulation in ETAP with different parameters of power system. On and offline power system has been developed and simulated successfully according to the data obtained from authentic sources at different times during day light. The obtained results of the load flow study are based upon Newton-Raphson Power flow solution.
