Abstract Co-simulation and Hardware-in-the-Loop, as well as the integration of Hardware-in-the-Loop to a co-simulation framework are innovative approaches that can get a step closer to a complete and realistic assessment and validation of cyber-physical energy system (i.e. smart grid). While the coupling techniques and the master algorithms ensure good functionality of the experiment, the whole framework has to follow a rigorous time semantic so that the results would be accurate and meaningful....
Abstract Despite their age, residential standard load profiles (SLPs) are a widely used tool to represent the electric power demand of a household. However, the prospect of a future power system relying mainly on renewable and often intermittent, distributed energy resources (DER) is pushing SLPs to their limit. Determining self consumption rates and the potential of demand response through smart home applications or simulating distribution grids, especially the low voltage (LV) level—all requir...
Abstract There is a knowledge gap about how the load modeling of smart grid affects the accuracy of the analytical reliability evaluation process and its calculation time. This paper tries to fill such a research gap by contributing to developing a methodology which is used to quantify the time reduction of the smart grid reliability assessment provided by various load state reduction strategies. In this paper, four novel load state reduction strategies (the aggregation of identical load states ...

Abstract Bipolar hybrid microgrid application is enhancing in power systems since this type of microgrid owns a DC and AC bus simultaneously, feeds local loads with local resources, and presents two dc voltage levels to users and resources. Interlinking converter (ILC) is the most important part of the microgrid structure due to its essential responsibilities in various applications. In this paper, a 10 switch converter is presented as an ILC for bipolar hybrid microgrid that advantages from bot...
Abstract A control strategy for the integration of photovoltaics (PV) and battery energy storage (BES) in a DC microgrid ( μ G) is proposed. The method provides a unique control architecture for both islanding and grid-connected modes. Moreover, the method does not require the operating mode signal to detect the islanding or grid-connected operation of the μ G. Consequently, it alleviates switching between different sets of controllers, thus providing a smooth transfer between operation modes. A...
Abstract Power quality improvement is an essential aspect of microgrids. In this paper, a cascaded voltage and current control scheme using the virtual impedance concept is proposed, which is capable of simultaneous quality improvement of local load voltage and grid-injected current. Also, the proposed control scheme is capable of working in both islanded and grid-connected modes with the ability of seamless transfer between them. In the proposed control scheme, the current controller is designe...

Abstract Internet of Things (IoT) is a new paradigm that has changed the way we live in our society by providing many intelligent applications such as smart healthcare, precision agriculture, smart city, smart supply chain, smart home, smart grid, and intelligent transportation. As an integration of smart grid and intelligent transportation, vehicle-to-grid (V2G) technology can make the power grid to communicate with the plugin electric vehicles (EVs), allowing the EVs to store greenpower energy...

Abstract Non-intrusive load monitoring (NILM) has been extensively researched over the last decade. The objective of NILM is to identify the power consumption of individual appliances and to detect when particular devices are on or off from measuring the power consumption of an entire house. This information allows households to receive customized advice on how to better manage their electrical consumption. In this paper, we present an alternative NILM method that breaks down the aggregated powe...

Abstract Nowadays, the deployment of grid-tied Lithium-ion Battery Energy Storage Systems (BESSs) is a promising technical solution to guarantee the security and reliability of the electric power system characterized by an increasing share of renewable sources. This paper studies BESS for Primary Control Reserve (PCR) provision by developing an approach to properly simulate BESS behavior. The proposed approach consists of a controller that elaborates the input signals (frequency fluctuations and...
