Topic: Analytic and hybrid methods Abstract Advances in microprocessor technology now make real time simulation with Hardware In the Loop (HIL) feasible for many applications. The literature is full of descriptions of how this technology has been applied to control systems [1]. In this paper we address two new aspects: • Interconnections between systems(More)
This paper presents the stability evaluation of a Simulation–Stimulation (Sim–Stim) interface that integrates hardware to software to perform Hardware-In-the-Loop (HIL) studies for testing and developing electrical equipment. Modeling issues of such an interface are discussed and a practical Sim–Stim interface model whose parameters are sampling rate and(More)

This paper presents a method for designing a Neural Network (") for potential application in real-time system security analysis. Specifically, we formulate the contingency classification problem as a pattern recognition problem and then design a NN to classify the system states (i.e., normal, alert and emergency). A two-layered NN with a fully-connected(More)

A novel method for exploring the power system saddle node and Hopf bifurcation boundaries in the space of active and reactive powers has been proposed in the paper. This method is of iterative type with an eigenvalue sensitivity approach used to find a first bifurcation point and a parameter continuation technique used to locate the entire saddle node and(More)
Lormetazepam (0.5, 1, 2, 4, 8 mg)--a new benzodiazepine--was tested versus Pentobarbital (100 mg) under double blind conditions on 240 preoperative inpatients for night-time sedative and side effects after acute oral intake. Results are based on p less than 0.05. Additionally p less than 0.125 in binomial-two-sample-tests was accepted. Lormetazepam shows(More)
