The harmonic currents produced by nonlinear loads and renewable energy sources (RES) like PV and wind energy have had a growing impact on industrial distribution networks in recent times. Along with harmonic distortions, lack of adequate reactive power support in a heavily loaded renewable‐rich industrial network has made the operation vulnerable to fault‐induced delayed voltage recovery (FIDVR). Due to poor post‐fault voltage recovery, an industrial microgrid is exposed to cascading loss of distributed generators (DGs). Dynamic var sources are being used to prevent cascade tripping. However, they may result in deterioration of the network's THD scenarios. Single tuned passive filters are widely used to suppress harmonic contents. The goal of this work is to design filters so that these become capable to lower overall harmonic distortion while also minimizing the risk of blackouts caused by inadequate post‐fault voltage recovery. To determine the allocation and rating of single tuned passive filters in a renewable‐penetrated industrial microgrid, an optimization model is developed. To show the feasibility and efficacy of the proposed formulation, simulations are performed on a modified IEEE 43 bus system. The findings suggest that the proposed design methodology produces effective solutions to minimize the necessity of additional reactive power sources.

Timely and effective location of faults in distribution networks is important for restoring power supply and dealing with faults. In this paper, a method combining matrix algorithm and genetic algorithm (GA) is proposed to determine the fault section. Firstly, the matrix algorithm is applied to locate the fault section initially by combining the alarm information uploaded from the feeder terminal unit (FTU). Secondly, in order to deal with the problem of outputting wrong location results, the switching function of the active distribution network is constructed to check the location results calculated by the matrix, and the results that do not meet the checking will be treated as a suspicious fault set, and the relevant evaluation function is constructed and optimized using the genetic algorithm, so as to arrive at the correct fault zone location results. The results of the example simulation show that the method used in this paper can achieve fast and fault-tolerant fault location in active distribution networks.

“…As alterações destas formas de ondas senoidais de tensão e de corrente são definidos como distorções harmônicas. O uso crescente de cargas não lineares conectadas a toda e qualquer rede elétrica, como os equipamentos eletrônicos, faz com que as distorções harmônicas cresçam a cada dia fazendo com que o desafio de identificar e corrigir níveis excessivos de harmônicos seja cada vez maior (Arrillaga e Watson, 2004), (Variz et al, 2008), (Variz et al, 2012), (IEEE, 2014).…”

“…Apesar dos seus múltiplos benefícios, como o aumento da matriz energética do país, essas fontes são associadasà uma notável intermitência eà diversos problemas de qualidade de energia, incluindo o aparecimento de distorções harmônicas (Peterson et al, 2017). Consequentemente, há uma necessidade de prover meios para a modelagem e representação dos componentes do sistema de potência no domínio da frequência (Variz et al, 2008), (Variz et al, 2012), (Levačić et al, 2019), (Melo et al, 2020), (de Melo et al, 2019), (Sharma et al, 2018).…”

Este trabalho compara modelos matemáticos utilizados para representação de uma linha de transmissão real, trifásica e transposta do sistema elétrico de potência brasileiro analisada no domínio da frequência considerando distorções harmônicas de tensão e corrente. Para tanto, é utilizado o modelo $\pi$ equivalente em componentes de fase, com correção hiperbólica, que garante a exatidão dos parâmetros da linha mesmo com a variação da frequência. Além desse modelo, são utilizados dois métodos desacoplados os quais representam modelos simplificados de transformação modal valendo-se da teoria de componentes simétricas de Fourtesque e de Clarke. Neste artigo, o desenvolvimento de cada modelagem é explicitado e resultados de simulação são validados através do uso do RTDS (Real Time Digital Simulator) assumindo injeções de correntes harmônicas e a análise da linha no domínio da frequência.
