In this paper, the effect of a static synchronous compensator (STATCOM) influence on the frequency of islanded microgrids based on frequency control using fuzzy cooperative control is investigated. To achieve fast frequency control, instantaneous power balance between generation and consumption is inevitable, and it can be supplied through energy storage systems such as battery with a proper fr...

Coordination of various distributed generation (DG) units is required to meet the growing demand for electricity. Several control strategies have been developed operate parallel-connected inverters microgrid load sharing. Among these techniques, due lack essential communication links between coordinate DG within a microgrid, droop method has generally accepted in scientific community. This pape...

In the hierarchical control of an islanded microgrid, secondary control could be centralized or distributed. The former control strategy has several disadvantages, such as single point of failure at the level of the central controller as well as high investment of communication infrastructure. In this paper a three-layer architecture of distributed control is given, including the device layer, ...

In this work, the optimization of an off-grid micro-hybrid system is evaluated. This conducted with estimation proper sizing each element and steady-state voltage, frequency, power responses microgrid. Kangaroo Island in South Australia considered to be test case location grid incorporates solar PV (photo-voltaic), diesel generator, battery storage, wind turbine. Optimal studied microgrid carri...

In modern infrastructure, the demand for DC power-based appliances is rapidly increasing, and this phenomenon has created a positive impact on the acceptance of the DC microgrid. However, due to numerous issues such as the absence of zero crossing, bidirectional behaviour of sources, and different magnitudes of fault current during grid connected and islanded modes of operation, protecting DC m...
