“…The anti‐islanding protection of the PV inverter will be triggered and disconnected from the network when the voltage and frequency of the islanded network exceed the boundary of Non‐detection Zone (NDZ) for a short duration as stated in the standards. The boundary for the NDZ is set in accordance with Malaysia standards, MS 1873 as shown in Figure …”

“…The boundary for the NDZ is set in accordance with Malaysia standards, MS 1873 as shown in Figure 5. 31 The NDZ as illustrated in Figure 5 depicts the boundary of NDZ of a PV inverter where over-frequency and underfrequency are fixed at 50.5 and 49.5 Hz respectively whereas the over-voltage and under-voltage are at 253.0 and 216.2 V respectively. For continuous operation of PV inverter, voltage and frequency have to be within the NDZ which is the grey region in Figure 5.…”

“…However, the authors of demonstrate that the fuzzy PID controller is able to minimise the frequency excursions much more effective than the conventional PI controller during islanded operation of the distribution networks. Besides, the simulation results from Choudhury et al show that the fuzzy logic controller provides much faster damping response than the conventional PI controller in regulating the frequency and voltage in the islanded network. Using energy storage system to provide frequency regulation can cause the batteries to undergo thousands of cycles in a year.…”

Summary Photovoltaic (PV) systems are expected to grow on the distribution networks in the future. Under the current regulatory frameworks, islanding operation of PV systems is not permissible because the frequency and voltage of the islanded networks are not regulated and maintained within the statutory limits during islanding operation. Consequently, PV systems must be disconnected immediately in the event of the grid outage as per Malaysian Standards, MS 1873. However, it is proven that the islanded operation of PV systems would enable the owners to consume the available solar energy and help the utility company improve the reliability of electricity supply. To enable the islanded operation of PV systems, a fuzzy‐based controller is developed to drive the operation of the energy storage system to maintain the frequency and voltage within the tolerances during the transition from grid‐connected to islanded operation. Several experimental case studies are performed to show that the fuzzy‐based controller is able to maintain the frequency and voltage within the statutory limits before the islanded networks are reconnected to the grid. It is also shown that the fuzzy controller performs more effective than the proportional‐integrator controller.

Este trabalho, constitui-se em uma contribuição para o estudo das estratégias de modulação direta baseadas em histerese e que funcionam em frequência fixa de comutação. Tem como objetivo principal propor a estratégia delta modificada, que diferencia-se na forma de ajuste da largura de banda de histerese, alterando-se seus limites e em como executa o comando de bloqueio das chaves de potência, para que a corrente de saída se mantenha em frequência fixa de operação e apresente rápida resposta dinâmica no sistema controlado. Para tanto, não necessita da utilização de derivadas, nem de uma corrente média de referência, tão pouco, se utiliza dos tempos de comutação. A estratégia proposta, comprova que é possível produzir os adequados pulsos de comando para o processamento da energia proveniente de célula combustível, através do conversor estático de potência, utilizando-se principalmente, dos valores de ultrapassagem nos limites estabelecidos de histerese. Como objetivo secundário desta pesquisa, desenvolve-se um conversor CC/CC auxiliar para adaptar e estabilizar a energia proveniente da CAC, compondo-se um sistema útil que serve de base para fornecer energia, aos mais diversos tipos de cargas em CC. Além disso, apresenta-se uma revisão das estratégias de modulação em modo direto para o controle da corrente de saída no conversor estático, tendo como base a tensão nos terminais de um indutor. Contudo, outras estratégias são naturalmente citadas, no transcorrer deste trabalho, devido haver combinações entre as diferentes estratégias moduladoras e controladoras comentadas.
