US power system is faced with proliferation of renewable generation in its transmission and distribution networks. Renewable energy integration in power systems have caused specific concerns for system planners and operators because of its intermittent and variable nature. This paper focuses on the benefits of using battery energy storage systems for the integration of wind energy. Several scenarios...
Multiple voltage regulating devices, such as on-load tap changer (OLTC), step voltage regulators (SVRs), switching capacitors banks work in tandem with each other to regulate voltage in the distribution network. These conventional devices are based on volt/var optimization strategies that work in a time coordinated method. However, in case of distribution systems with Photovoltaic (PV) generations,...
Growing numbers of utilities are experiencing proliferation of Plug-in Electric Vehicles (PEV) and Photovoltaic Distributed Generation (PV-DG) in their distribution systems. Charging patterns of PEVs tend to increase the original day-time and evening peak demands of distribution feeders, while PV-DG units are highly intermittent energy sources. Therefore, the integration of large amount of PEVs and...
The utility industry is expecting a proliferation of Plug-in Electric Vehicles (PEV). This has prompted increasing interest in evaluating the potential impacts of PEVs on power distribution system planning and operations, as well as in proposing mitigation approaches that allow their seamless integration. In addition, there is a noticeable growth in the number of solar photovoltaic distributed generation...
Rapid growth of grid-connected photovoltaic distributed generation (PV-DG) provides many benefits such as clean energy, reduced emissions and creation of new green jobs. However, given its intermittent nature, large scale penetration of PV-DG may challenge the quality and reliability of the grid. This paper evaluates the impact of PV-DG on distribution system voltages. The paper describes the models...
