Solution of Different Types of Economic Load Dispatch Problems Using a Pattern Search Method

Direct search (DS) methods are evolutionary algorithms used to solve constrained optimization problems. DS methods do not require information about the gradient of the objective function when searching for an optimum solution. One such method is a pattern search (PS) algorithm. This study presents a new approach based on a constrained PS algorithm to solve various types of power system economic load dispatch (ELD) problems. These problems include economic dispatch with valve point (EDVP) effects, multi-area economic load dispatch (MAED), companied economic-environmental dispatch (CEED), and cubic cost function economic dispatch (QCFED). For illustrative purposes, the proposed PS technique has been applied to each of the above dispatch problems to validate its effectiveness. Furthermore, convergence characteristics and robustness of the proposed method has been assessed and investigated through comparison with results reported in literature. The outcome is very encouraging and suggests that PS methods may be very efficient when solving power system ELD problems

Achieving the Dispatchability of Distribution Feeders through Prosumers Data Driven Forecasting and Model Predictive Control of Electrochemical Storage

We propose and experimentally validate a control strategy to dispatch the operation of a distribution feeder interfacing heterogeneous prosumers by using a grid-connected battery energy storage system (BESS) as a controllable element coupled with a minimally invasive monitoring infrastructure. It consists in a two-stage procedure: day-ahead dispatch planning, where the feeder 5-minute average power consumption trajectory for the next day of operation (called \emph{dispatch plan}) is determined, and intra-day/real-time operation, where the mismatch with respect to the \emph{dispatch plan} is corrected by applying receding horizon model predictive control (MPC) to decide the BESS charging/discharging profile while accounting for operational constraints. The consumption forecast necessary to compute the \emph{dispatch plan} and the battery model for the MPC algorithm are built by applying adaptive data driven methodologies. The discussed control framework currently operates on a daily basis to dispatch the operation of a 20~kV feeder of the EPFL university campus using a 750~kW/500~kWh lithium titanate BESS.Comment: Submitted for publication, 201

Clark Praises Judicial System

WILLIAMSBURG -- Former U.S. Supreme Court Justice Tom C. Clark said here Wednesday that he hoped there was no obstruction of justice on the part of President Nixon during the Watergate affair. Talking to reporters following a program at the College of William and Mary, Clark said that obstruction of justice is one of our gravest offenses, because it destroys the very system we live by. He said that he had not read all the details of the Watergate tape transcripts. His comments on Watergate were made in response to a question regarding Nixon and discussions with aides about hush money for Watergate defendant E. Howard Hunt. I\u27m not saying there was any kind of obstruction of justice, Clark emphasized, I\u27m just saying that I hope it didn\u27t occur. Clark was on the Supreme Court from 1949 until he retired in 1967. The recent trial of former Atty. Gen. John N. Mitchell and former Commerce Secretary Maurice H.Stans showed the strength of our judicial system in that 12 people have the courage to stand up and make important decisions, he said. Clark was on the W&M campus Wednesday as part of Law Day 1974 program sponsored by the Marshall-Wythe School of Law here, the W&M Student Bar Association and the Norfolk-Portsmouth Bar Association. During the ceremony, Clark was recognized as one of the nation\u27s most successful and illustrious jurists by Dean James P. Whyte of the Marshall-Wythe School of Law, who presented Clark with the school\u27s Marshall-Wythe medallion, an award reserved for selected leaders of the legal profession. As another part of the Law Day observance, Judge John A. MacKenzie, federal district judge for the eastern district of Virginia, presided over a special session of Federal District Court convened here to naturalize 124 persons from the Tidewater area as U.S. citizens. Following the ceremony, Clark spoke to about 400 persons. He said that the great test of democracy is what it puts in the hearts, minds, and purposes of its citizens

Bucknell Honors W&M Law Dean

WILLIAMSBURG -- James P. Whyte, Jr. dean of the Marshall-Wythe School of Law at the College of William and Mary, was given an award Saturday by Bucknell University for meritorious achievement. The award to Whyte, a member of the Bucknell class of 1943, was for his practical vision in legal education and his abilities as a labor-management arbitrator and specialist in constitutional and criminal law. Whyte earned his law degree from the University of Colorado and has been a member of the W&M law school faculty for 16 years and dean since 1970
