“…The ADRC is designed in a higher-order system by deriving the algebra of polynomials from the transfer function in order to facilitate the analysis. Therefore, an equivalent model of Equation (2) is essential in the polynomial form to implement ADRC for the plant of Equation (1). In the generalized disturbance term, any error between the two models can be considered.…”

“…These balances drive two equilibrium points: frequency and voltage. Stable operation of interconnected power system requires both acceptable frequency and tie-line power exchange [1]. Load frequency control (LFC), which is mainly used to maintain the standard frequency and the tie-line power exchange under schedule during any load changing event, can be defined as regulation of active power and frequency [2].…”

System frequency may change from defined values while transmitting power from one area to another in an interconnected power system due to various reasons such as load changes and faults. This frequency change causes a frequency error in the system. However, the system frequency should always be maintained close to the nominal value even in the presence of model uncertainties and physical constraints. This paper proposes an Active Disturbance Rejection Controller (ADRC)-based load frequency control (LFC) of an interconnected power system. The controller incorporates effects of generator inertia and generator electrical proximity to the point of disturbances. The proposed controller reduces the magnitude error of the area control error (ACE) of an interconnected power system compared to the standard controller. The simulation results verify the effectiveness of proposed ADRC in the application of LFC of an interconnected power system.

“…The electrical distances once specified can be used to determine the zones and pilot nodes of the secondary (regional) voltage control which is widely accepted and has been implemented in some European systems, for example in France [20] and Italy [21]. As a matter of fact, attenuation factors computed by EDF do not reflect well the systems under heavy load conditions [22]. The following method is developed to overcome these situations.…”

-Recently, Korean system operating conditions have gradually approached an upper limit.When a contingency occurs, the power system may have no solutions. Different from the cases of bad initial guesses or the solutions are too close to the solvability boundary in which numerical methods can be applied, for unsolvable cases, the only way to restore solvability would be structure modifications. In this paper, a new approach for corrective and preventive control to such cases is proposed in two steps: (i) finding any solution regardless its feasibility; (ii) for the infeasible solution, make it feasible with additional modifications at load buses having Distributed Energy Resources. The test case built based on the peak load profile of 2008 by KEPCO including 1336 buses is analyzed. Since reactive power compensation is optimized to restore solvability, all demands are met, therefore no blackouts happen. The proposed method was integrated in the LP program designed by power21 Corporation.

“…É certo, porém, que nesses mais de 30 anos de evolução dos sistemas de controle e monitoramento muitos conceitos foram criados, bem como novas alternativas para redução de custos com tais sistemas foram implementadas (Tomsovic, 2005). Acompanhando as tendências de um moderno sistema de supervisão e controle da distribuição, almeja-se disponibilizar aqui um sistema integrado que auxilie os operadores do sistema de distribuição a tomarem decisões mais acertadas, contribuindo assim para o aumento dos índices de desempenho e, consequentemente, aumento do nível de satisfação de seus clientes.…”

2013Trata-se da versão corrigida da tese. A versão original se encontra disponível na EESC/USP que aloja o Programa de Pós-Graduação de Engenharia Elétrica. O objetivo deste trabalho é estudar a identificação, classificação, localização e setorização de faltas em redes de distribuição radiais, verificar a maneira de aplicar e integrar diversas ferramentas numéricas convencionais, assim como ferramentas de sistemas inteligentes, visando identificar a ocorrência de uma falta, classificar as fases envolvidas com a mesma, e aplicar as diversas ferramentas existentes a fim de localizar em tempo real o eventual local onde houve a ocorrência da falta, permitindo que a mesma possa ser setorizada dentro do sistema da concessionária e informada ao centro de operações, usando uma nova abordagem inteligente baseada em análise espectral de sinais.
