“…However, in the case of weak grid, voltage control with DSTATCOM requests high reactive power due to high R/X line grid ratio, making reactive power control less powerful in low voltage grids. This factor gives rise to two major issues: the need for a converter with especially high rated power to ensure control and the excessive reactive power circulation in the distribution transformer, which can damage equipment [2]. Static compensator with thyristor switched capacitors and thyristor control reactors are more advanced configurations with a continuous control, basically no transition voltage, minor generation of harmonics, and control and operation flexibility [26,33].…”

“…ESS can flexibly adapt at different time scales and may be considered as a variable energy source or variable load [54]. ESS may be operational at specific times or in critical situations [2,55]. These multifunctional optimizations enhance the reliability of power grid, considering the issues faced by transmission and distribution networks [56].…”

“…These problems are common for electricity distribution networks [1]. Voltage drop is among the most important energy quality issues and concerns users connected to low voltage distribution grids [2]. Voltage stability is closely linked with changes in load dynamics, and lately, constant changes in system loads have been giving rise to a greater number of voltage instability cases.…”

The traditional unidirectional, passive distribution power grids are rapidly developing into bidirectional, interactive, multi-coordinated smart grids that cover distributed power generation along with advanced information communications and electronic power technologies. To better integrate the use of renewable energy resources into the grid, to improve the voltage stability of distribution grids, to improve the grid protection and to reduce harmonics, one needs to select and control devices with adjustable reactive power (capacitor batteries, transformers, and reactors) and provide certain solutions so that the photovoltaic (PV) converters maintain due to voltage. Conventional compensation methods are no longer appropriate, thus developing measures are necessary that would ensure local reactive and harmonic compensation in case an energy quality problem happens in the low voltage distribution grid. Compared to the centralized methods, artificial intelligence (heuristic) methods are able to distribute computing and communication tasks among control devices.

“…O sistema de controle de corrente realiza a injeção de corrente no PCC de forma a absorver ou fornecer potência reativa para a rede de distribuição. No modo de controle de corrente, o próprio controlador se encarrega de limitar a corrente de saída do DSTATCOM, sem a adição de outras técnicas [7] [8]. Essa característica do sistema de controle de corrente aumenta a imunidade do DSTATCOM frente a uma situação de curto-circuito no PCC, que pode ocasionar o desligamento ou, até mesmo, danos permanentes ao conversor.…”

Resumo-Os compensadores de reativos controlados em tensão operando em redes de distribuição de energia estão suscetíveis a distúrbios de tensão (afundamentos, elevações, surtos, interrupções e curto-circuito), assim, é possível que estes venham a processar correntes elevadas, podendo levar ao seu desligamento ou, até mesmo, torná-los inoperantes. Esse trabalho apresenta um novo conceito de Resistência Virtual Não Linear aplicado a um DSTATCOM (Distribution Static Synchronous Compensator) controlado em tensão. A técnica limita a potência de saída do conversor por meio da limitação de corrente do conversor. Em condição normal de operação, a técnica não altera a resposta dinâmica da malha de tensão. O conceito proposto permite que o DSTATCOM permaneça operante em condições de distúrbios da rede elétrica, protegendo o conversor e as cargas próximas ao ponto comum de conexão. O trabalho é concluído com a implementação da técnica em um protótipo de 10 kVA. A validação da proposta por meio de resultados experimentais obtidos comprova o bom funcionamento do limitador de corrente em condição de distúrbios.
