Abstract

This paper briefs about partial shading condition and different methods in literature which can be used under partial shading condition. This will be helpful for all who want the idea of partial shading condition and also get a fair idea about different techniques available and also update themselves with current happenings about MPPT.

Abstract

Classical Control Theory (CCT) is one of the general education courses for many university engineering curricula. Course contents usually have deep theoretical definitions, high level of abstraction, computationally intensive procedures and demand students with a solid mathematical background. In the present paper, we explore how animation has the potential to contribute to the learning and comprehension of several contents included in a CCT introductory course. Based on current theories of multimedia learning, we incorporated animation components in modules designed for teaching various educational contents. Animation is an efficient didactic tool for explaining theoretical definitions, underlying methodologies involved in diagrams construction and computational procedures described on a CCT introductory course. We recommend that animation should be included in every CCT educational software.

Abstract

This paper presents a geometric parameterization technique for the continuation power flow that allows the complete tracing of P-V curves and the calculation of the maximum loading point of power systems, without singularity problems of Jacobian matrix (J). The technique will be started from the “flat start”, i.e., the voltage magnitude of all the buses PQ are placed in 1.0 p.u. and the angle bus voltage of all the buses are placed at 0º (zero degree). To eliminate the singularity has been added to the equation of a line passing through a point in the plane determined by the variable load factor and the sum of all the bus voltage magnitudes. The results obtained with the technique to ill-conditioned systems (11 buses), IEEE test systems (300 buses) and the 638-bus system corresponding to part of South-Southeast Brazilian system, improve the characteristics of the conventional method and extend the convergence region around the singularity.
