Abstract

In this paper, the modelling and control of a DC motor using MATLAB software (Simulink and SISO Design Tool) is carried on. The Simulink environment is used for modeling the motor and SISO Design Tool is used for controlling the motor by automate tuning of the controllers. The tuned controllers are PI (Proportional-Integral), PD (Proportional-Derivative) and PID (Proportional-Integral-Derivative). The controllers need to be tuned for improving the performance of a system and designing the controller requires system mathematical modeling. [ABSTRACT FROM AUTHOR]

Abstract

Transmission expansion planning has the purpose to ensure two important objectives: economic trade and engineering reliability and also, in this paper, it establishes the optimal expansion decisions in a large real network with classical generators and high share of RESs. The proposed problem is a mixed-integer nonlinear programming problem (MINLP) that is resolved using a deterministic model considering a threshold budget for new transmission lines that are possible to be built. The objective of the mathematical model presented in this paper is to decrease the entire operational cost of the power system. The considered model was solved using GAMS (General Algebraic Modeling System) optimization software and it can be modified to enable the independent system operator (ISO) to adjust to future electrical network modifications.
