A General Approach for Security Monitoring and Preventive Control of Networks with Large Wind Power Production

This paper provides a description of the development of software tools able to deal with system fast dynamic monitoring and determination of preventive control procedures, for a given set of disturbances, in networks with large integration of wind power production. Preventive control is performed through power redispatches, involving also the on/off control of the wind generators. The quality o...

A NEW APPROACH TO THE SOLUTION OF SENSITIVITY MINIMIZATION IN LINEAR STATE FEEDBACK CONTROL

In this paper, it is shown that by exploiting the explicit parametric state feedback solution, it is feasible to obtain the ultimate solution to minimum sensitivity problem. A numerical algorithm for construction of a robust state feedback in eigenvalue assignment problem for a controllable linear system is presented. By using a generalized parametric vector companion form, the problem of eigen...

Risk Based Voltage Security Assessment

The objective of this paper is to provide a risk-based approach to security assessment for a voltage stability constrained power system. It is motivated by a perception that today’s deterministic reliability criteria to voltage stability assessment often results in operating restrictions that are not commensurate with the corresponding level of risk. The risk calculation provided in this paper ...

Voltage Stability Assessment using GVSM and Preventive Control using SVC

Voltage stability is a major concern while designing a foolproof power network. In recent years deregulated environment put an additional pressure on transmission and distribution utilities. With this fact assessment of voltage stability along with the preventive control actions are major area of research. With this motivation, this paper presents assessment of voltage stability through Global ...
