“…EUSBS is designed as a unified interface access platform for a plugand-play of DEE and an IEM system for a deep information-energy interaction analysis between DEE and power grid. The meaning of plug-and-play has three technical aspects [58][59][60][61]: (a) it is similar to the USB computer interface protocol and has a rapid perception and description ability for the load equipment, energy storage and power generation, etc. ; (b) it has an open hardware platform and is easy to connect with the current power grids; (c) it can automatically and rapidly access or disconnect from the energy flow and information flow under the circumstances the DEE are in access or in disconnection status, respectively.…”

This paper develops a novel energy universal service bus system (EUSBS) based on emerging energy Internet (E-net) technologies. This EUSBS is a unified identification and plug-andplay interface platform to which high penetration distributed energy and equipment (DEE), including photovoltaic (PV), fans, electric vehicle charging stations (EVCSs), energy storage equipment (ESE), and commercial and residential users (CRUs), can access in a coordinated control and optimized utilization mode. First, the functions design, overall framework and topology architecture design of the EUSBS are expounded, among which the EUSBS is mainly composed of a hardware system and a software platform. Moreover, several future application scenarios are presented. Then, the hardware part of EUSBS is designed and developed, including the framework design of this hardware subsystem, and development of the hardware equipment for PV access, fans access, EVCS access, ESE access, and CRU access. The hardware subsystem consists of smart socket, and household/floor/building concentrators. Based on this, the prototypes development of EUSBS hardware equipment is completely demonstrated. Third, the software part of the EUSBS is developed as a cloud service platform for electricity use data analysis of DEE. This software subsystem contains the power quality & energy efficiency analysis module, optimization control module, information and service module, and data monitoring and electricity behavior analysis module. Based on this design, the software interfaces are developed. Finally, an application study on energy management and optimization of a smart commercial building is conducted to evaluate the functions and practicality of this EUSBS. The EUSBS developed in this paper is able to overcome difficulties in big data collection and utilization on sides of distribution network and electricity utilization, and eventually implement a deep information-energy fusion and a friendly supplydemand interaction between the grid and users. This contribution presents a detailed and systematic development scheme of the EUSBS, and moreover, the laboratory prototypes of the hardware and software subsystems have been developed based on E-net technologies. This paper can provide some thoughts and suggestions for the research of active distribution network and comprehensive energy management and optimization in power systems, as well as references and guidance for researchers to carry out research regarding energy management, optimization and coordinated control of the smart buildings.

“…This has led to extensive research on bidirectional PEV chargers that feature grid-tovehicle (G2V) operations for battery charging as well as vehicle-to-grid (V2G) operations. V2G operations of bidirectional PEV chargers are highly attractive due to the potential of PEVs fulfilling the energy storage needs of the grid and assisting the grid in terms of providing active power for load leveling, reactive power support, ancillary services, voltage regulation, harmonic filtering and power factor correction [7][8][9][10][11][12][13][14]. Supplying reactive power using on-board chargers that are connected to a distribution system has some inherent disadvantages, such as the mobility and the power limitation of on-board chargers [15,16].…”

This paper presents a model predictive control (MPC) for off-board plug-in electric vehicle (PEV) chargers with photovoltaic (PV) integration using two-level four-leg inverter topology. The PEV charger is controlled by a unified controller that incorporates direct power and current MPC to dynamically control decoupled active-reactive power flow in a smart grid environment as well as to control PEV battery charging and discharging reliably. PV power generation with maximum power tracking is seamlessly integrated with the power flow control to provide additional power generation. Fast dynamic response and good steady-state performance under all power flow modes and various environmental conditions are evaluated and analyzed. From the results obtained, the charger demonstrates less than 1.5% total harmonic distortion as well as low active and reactive power ripple of less than 7% and 8% respectively on the grid for all power flow modes. The PEV battery also experiences a low charging and discharging current ripple of less than 2.5%. Therefore, the results indicate the successful implementation of the proposed charger and its control for PV integrated offboard PEV chargers.

“…The need of improving energy efficiency and fuel efficiency further catalyzed the automotive sector to develop EVs; this will increase the number of EVs in the near future. For instance, the U.S. Department of Energy estimates that there will be more than 1.5 million by the end of 2016 [3,4]. The EV, either in the form of the plug-in hybrid electric vehicle (PHEV) or battery electric vehicle, allows the energy storage units (ESU) to be charged either through the electrical grid during vehicle downtimes, or by renewable power sources [5][6][7].…”

Electric vehicles (EV) are being commercialized to overcome engine emissions and boost performance of vehicle. Peak power management of grid is also accomplished through EVs with vehicle-to-grid (V2G) and vehicle-to-home (V2H) capabilities. In a smart grid environment, these strategies assist in managing peak load management of the grid and home respectively. This paper proposes the use of EV as a regular standby power supply for home in addition to its use as an EV. EVs availability and usage developed by different drive patterns and operating modes of the vehicle. Unscheduled charging of the EV through grid case too much stress on the grid, so the ability of the vehicle to take power from the roof mounted solar panel and feed to the domestic load in different seasons of the year is discussed. The hardware in the loop model of the proposed home-to-vehicle (H2V) system is developed and results are obtained for different operating modes. The obtained result has shown significant promise to the suggested H2V strategy.
