If we look at the history of renewable energy sources (RESs), how it all began, and how rapidly they continue to develop, it can be argued that one of the main reasons is due to the rapid improvements in power electronics technology in interfacing the renewable source to the grid [...]

A Power System is actually a vast system that requires an outstanding plan for maintaining the continual flow of electricity. When a fault occurs at the power system, number of difficulties arises because of transients in system. so to attenuate these transients, power electronics based devices like FACTS are utilized. A unified power flow controller (UPFC) is one among different power electronics controller which can dispense VAR compensation, line impedance control and phase shifting. The thought is to see potential of UPFC to require care of active and reactive power movement within the compensated line (including UPFC) and to shrink the falloff of the bus voltage in case of grounding fault within the cable. power system block consisting of simulink is used for numerical analysis. Simulation outcomes from MATLAB reflects major improvement in the overall system’s behaviour with UPFC in sustain the voltage and power flow even under severe line faults by proper injection of series voltage into the cable at the point of connection. outcomes shows how the UPFC contributes effectively to a faster regaining of the power system to the pre-fault conditions.

Integrated standardization theory has been applied to work on integrated standardization for the Smart Grid Scheduling and Controlling System (SG-SCS), aiming to improve the overall quality and coordination of technical standards for dispatching and controlling in power system which help to solve practical problems. This Paper presents the definition and history of integrated standardization, and introduces the method to develop integrated standardized work for the SG-SCS which contains 4 phases: preparation phase, planning phase, standard setting or revising phase and organizing and implementing phase. The objects for integrated standardization is analyzed and determined, while the objective is addressed as well. Analysis elements related to the SG-SCS systematically and ascertain the scope of those, for target decomposition of integrated standardization. Make the complex of standards plan based on former results and determine what standards we shall set or revising. Create a detailed work plan and execute it to form a coordinated complex of technical standards. Organize the implementation of standards, with a close-looped feedback work mechanics, the overall quality and reliability of standards for SG-SCS can be ensured. By carrying out the SG-SCS integrated standardization, problems such as partly duplication or Contradiction between old standards, the overall quality of standards is promoted, which helps to the operation and control of electrical power system.
