Real Time Modeling and Control of Smart Grid Systems

Abstract

AbstractThe real time modeling and simulation of smart grid behavior under the disturbance helps in the analysis and planning of system in order to minimize the possible damage. Real time modeling and simulations with hardware in the loop capabilities allows testing the smart grid control algorithms and new equipments.This chapter addresses two aspects of smart grid modeling and simulation. First one relates to the development of wide area monitoring and control (WAMC) test bed including phasor measurements units (PMUs), synchophasor vector processor (SVP), phasor data concentrators (PDC) and real time digital simulator (RTDS). A WAMC system provides improved reliability, security and coordinated control actions to mitigate or prevent large area disturbances. PMU technology is being deployed all over the world by different utilities for wide area measurement and control actions. These units are mainly based on time synchronized measurements of voltages and currents that lead to accurate decisions and faster control actions. RTDS was used to model and simulate power system and PMUs was used to generate measurement data for power system monitoring. Measured data was sent to PDC and SVP for further analysis and control. Developed WAMC test bed can also be used for testing control algorithm and device performance. Second aspect of this chapter relates to modeling and simulation of Microgrid. Microgrid with controllers have been modeled and simulated in MATLAB/ Simulink.KeywordsPower SystemSmart GridMaximum Power PointReal Time ModelingPhasor Measurement UnitThese keywords were added by machine and not by the authors.
