Integrated monitoring and control of energy storage and other generating sources and loads in microgrids are important to ensure full realization of the benefits of energy storage. This paper describes ongoing projects at the University of California – San Diego (UCSD), 42 MW microgrid that integrates energy storage and associated monitoring and control. The UCSD microgrid power distribution sy...

This paper intends to improve the accuracy of power system State Estimation (SE) by introducing a hybrid linear robust state estimator. To this end, automatic bad data rejection is accomplished through an M-estimator, i.e. Schweppe-type estimator with Huber loss function. The method Iteratively Reweighted Least Squares (IRLS) used maximize likelihood function in M-estimator. Leverage measuremen...

Accurate state estimation is essential for correct supervision of power grids. With the existence cyber-attacks, may become inaccurate, which can eventually lead to wrong supervisory decision making. To detect cyber-attacks in grids equipped with phasor measurement units (PMUs), a new intrusion detection system based on clustering approach, called PMU Intrusion Detection System (PMUIDS), propos...

in this article, a multi-objective function for placement of distributed generation (dg) and capacitors with thetap setting of under load tap changer (ultc) transformer is introduced. most of the recent articles have paidless attention to dg, capacitor placement and ultc effects in the distribution network simultaneously. insimulations, a comparison between different modes was carried out with,...

The issue of power system voltage stability, which is one the key issues in process planning and operation system, considered paper. It noted that neural networks have now been tested a number technological incidents form instability various countries. problem possible risk failure due to loss its stability energy during investigated. this regard, conducting analysis an important procedure orde...

The increasing demand of load without considerable increase in transmission resources has posed numerous constraints and challenges in the power system monitoring and performance. The inadequacy in transmission resources has resulted in reduced operational margins for many power systems worldwide and has led to operation of power systems closer to their stability limits and to power exchange in...
