Application areas such as electric vehicles, data centers and microgrids increasingly rely on power electronic converters and electric motor drives to control loads. These tightly regulated converters act as Constant Power Loads (CPLs) in the context of the entire system. The negative incremental impedance of a CPL causes inherent instability which may lead to a grid collapse. This paper reviews the...
Residential microgrid load modeling is a new challenge that has received increased attention in recent years. Traditional state-of-art load modeling methods are not able to reflect the details of the residential loads proficiently. In addition, microgrid load modeling serves as a foundation for emerging smart grid technologies, such as microgrid planning, smart building design and demand-side energy...
Microgrids are smaller grid networks that supply power locally. They are connected to primary power grids and are able to manage electricity between primary and local electricity generation, maximizing the systems efficiency in order to help successfully supply loads. Although some microgrids use diesel generators, with increasing interests in renewable energy sources, interconnections with wind and...
This paper provides a comprehensive study on the deployment of the retired Hybrid Electric Vehicle (HEV) battery in residential applications. First, the paper proposes an algorithm for determining the optimal usage profile of the battery pack for a residential house equipped with a roof-top PV system. The proposed algorithm, which is derived from the optimal control theory, minimizes a cost function...
A hybrid Microgrid testbed that combines Power Hardware-in-the-Loop (PHIL) simulation of electric power network and System-in-the-Loop (SITL) simulation of communication network with real hardware is presented in this paper. The PHIL system can interface with other power hardware and emulate different systems connected to the testbed, such as renewable energy conversion systems, different topologies...
