A repetitive controller (RC) is one of the most promising candidates for harmonic compensation when designing current grid-connected inverters. The discrete-time closed-loop transfer function based frequency response method can be used to shape RC, which applicable a single inverter connecting well-known inductive-impedance grids, but cannot guarantee stability in case capacitive-impedance grid...

The review of inverter is developed with focus on low cost, high reliability and mass-production for converting electrical energy from the pv module to the grid. Various inverter topologies are presented, compared, and evaluated against demands, lifetime, component ratings, and cost. Inverter based PV system to explain electrical performance subjected to different operating conditions. Multilev...

From the Internet of Energy point of view, adjacent building combined cooling, heating and power with microgrids (BCCHP microgrids) should be interconnected, which will generate better benefits, both economically and environmentally, from scarce energy resources through intelligent coordination. The interconnected-BCCHP (IBCCHP) microgrids will not only support energy with each other but also b...

Two interconnected AC microgrids are proposed based on three renewable energy sources (RESs): wind, solar, and biogas. The wind turbine drives a permanent magnet synchronous generator (PMSG). A solar photovoltaic system (SPVS) with an appropriate inverter was incorporated. biogas genset (BG) consists of engine coupled generator. microgrids, M1 M2, were considered for study in this work. microgr...

This paper presents an auxiliary passive circuit and control design for wireless power transfer (WPT) systems in DC microgrids to achieve optimal efficiency while maintain accurate output voltage regulation. An inductance is added at the transmitter resonator form a current sink ensure zero switching (ZVS) of primary-side full-bridge inverter with even extremely light load conditions. Moreover,...

Microgrids are eco-friendly power systems because they use renewable sources such as solar and wind power as the main power source. However, the stochastic nature of wind and solar power is a considerable challenge for the efficient operation of microgrids. Microgrid operations have to satisfy quality requirements in terms of the frequency and voltage. To overcome these problems, energy storage...

Nowadays, the penetration of distributed generations (DGs) and microgrids (MGs) has been significantly increased due to technical, social, environmental, financial reasons. One most common types DGs which is widely used in different networks small-scale synchronous generators (SSSGs). Synchronous-based (SGBMGs) SSSGs can operate under both grid-connected islanded conditions. To guarantee a stab...
