Abstract
AbstractDistributed generation (DG) specifically from solar energy is gaining much attention. Integration of solar photo-voltaic plant (SPP) on distribution grid increases flexibility of the system...
Highlights
Distributed renewable energy generation is small power-generating unit clubbed with modern technologies and present diverse challenges while integrating with utility grid Most of the renewable energy sources (RESs) shall be located near load centre on distribution grid
The power flow depends on health of solar photo-voltaic plant (SPP) and their placement on distribution grid
The operation time of relays is calculated through plug-setting multiplier (PSM) and (α,β) constants and optimized operating time of the relay is calculated through optimizing the main function of the relay with respect to various constraints
Summary
Distributed renewable energy generation is small power-generating unit clubbed with modern technologies and present diverse challenges while integrating with utility grid Most of the renewable energy sources (RESs) shall be located near load centre on distribution grid. This paper calculates time multiplier setting (TMS) and relay tripping time for integrated SPP distribution grid through predetermine value of pick up current setting. The issue that occur often is islanding, which can be removed with the help of updating protection scheme as per number of RES interconnection This kind of protection scheme is known as adaptive protection scheme Step 5 calculates the TMS/TDS for relay with respect to coordination time interval (CTI) and fault current at different locations
