Smart utilization of renewable energy sources in a microgrid system integrated with plug-in hybrid electric vehicles

Abstract

Summary Mass roll‐out of plug‐in hybrid electric vehicles (PHEVs) and significant penetration of renewable energy sources in distribution system play a major role in delivering low carbon environment. However, placing and utilizing these units randomly result in overloading, increased power loss, and reduced voltage profile. This paper responds to these technical challenges by using a strategic placement method for locating the distributed generation (DG) and the charging station (CS) of PHEVs in a multi‐zone distribution system. For simultaneously scheduling of these units in each zone, the smart energy management framework is proposed in this paper. Apart from usual energy management constraints, this paper also incorporates the real‐time constraints involving the capacity of PHEV batteries, the mobility pattern, and the power level of the charging infrastructure. The simulation studies are carried out for each hour of a day. To cope with this time constraint execution, particle swarm optimization algorithm‐based approach is used. The proposed framework is tested in IEEE 33 and IEEE 69 bus radial distribution system. The obtained results imply that the presented energy management framework provides maximum profits for the vehicle owner, and meanwhile it fulfills preferences of the user in each zone simultaneously.

Demonstrating the benefits of thermoelectric‐coupled solar PV system in microgrid challenging conventional integration issues of renewable resources

“…The hybrid nonconventional distribution generation (h-NDG) is generally based on power generation from locally available renewable resources, which may either be connected to the grid or isolated from the grid. Considering the design of nonconventional power generation and picking up of accurate components to achieve load demand and energy requirement economically as well as effectively has been outlined in Suganya et al 23 Violation of the microgrid concept comes into picture whenever the hybridized system will be unable to cope with the sources availability. 20 In order to mitigate the technical challenges like increment in power loss and system overloading, reduction in voltage profile using strategic placement of RE generators have been explained in Beeri et al 21 Similarly, to improvise performance of the system degrading the environmental impact, several numbers of outputs have been derived from multihybridization of RE sources.…”

Modeling and operation optimization of RE integrated microgrids considering economic, energy, and environmental aspects

“…Further, the work in Zhang et al presented a robust model to accommodate high penetration of RE sources. In Suganya et al, the authors presented a microgrid model for smart utilization of RE sources. However, the work was focused to investigate the microgrid performance with hybrid electric vehicles.…”

Biofuel supply chain optimal design considering economic, environmental, and societal aspects towards sustainability

“…1 This process can relieve the environmental concerns of energy systems towards sustainability. 2 In addition, compared to other renewable sources like wind and solar energy, [3][4][5][6][7][8] bioenergy also has the advantage of serving as an energy buffer for optimizing the power grid during peak load periods. 9 Both the government and academia have considered biofuel as a promising alternative to traditional fossil fuels for building a sustainable global energy supply system, which means it will not compromise future generations' ability to meet their needs of energy when meeting today's energy needs for environmental stewardship, economic prosperity, and quality of life.…”
