The increase of faster dynamics in power systems has led to growing interest in new simulation solutions, especially in the field of hardware-in-the-loop and real-time simulation. Due to the size of power systems, detailed simulation of the faster dynamics is only feasible for a section of the system, whereas the rest is usually modeled as an infinite power bus. The aim of this work is to present a solution which would allow the representation of a significant portion of the dynamics that are usually not captured by the infinite power bus approach and enable the joint simulation among multiple simulation laboratories to share this dynamic model of the network beyond the boundaries of the detailed simulation. Furthermore, the presented architecture should allow the virtualization of each of these laboratories in cases where this coarse model of the neighboring grid sections is sufficient. First distributed simulation examples show the current status of our implementation of the architecture presented here.

The MMC based energy storage device is a type of bi-directional power device. Both the MMC and the energy storage device are key infrastructures in the future medium and high voltage networks. The MMC converter enables the capability of embedding the battery into the sub-module of the MMC distributively. The MMC based energy storage device employs the MMC converter as the power exchange interface and the battery as energy storage device. An active control scheme for the MMC based energy storage device consists of the bi-directional power interface topology and the active control strategy. The bi-directional power interface in the device is established based on the MMC sub-module and the buck-boost circuit. The active control strategy consists of the MMC grid-connection control method and the energy storage control method. The MMC based energy storage device can buffer the power fluctuation in the applications of renewable energy grid-connection or power transmission between the AC grid and the DC grid.

This paper discusses the effect of calendar aging on the growth rate of SEI. It discusses the reasons for the growth of SEI and the implementation of SEI growth in the 3D First Principle Based Degradation Model (3DM) of the battery. The growth of SEI is simulated over a period of 3 years and the impact it has over the terminal voltage and current generated by the battery are plotted and discussed. The results are then applied to the Equivalent Circuit Model (ECM) of the battery to study and identify the impacts that calendar aging and SEI growth has on the parameters of the circuit. The increase in the internal resistance and the decrease in the capacity are also discussed.

The traditional method for interconnecting PV and a battery energy storage system (BESS) to a household load uses at least two separate converters. In this paper, a fully-isolated three-port converter (TPC) which is based on a dual active bridge (DAB) configuration is proposed for integrating the PV and BESS with the household loads to avoid multistage power conversion. A converter with more than two ports is normally designed to have multimode operations which requires multiple control loops. Due to these multiple cross-coupled power control loops, designing closed loop power control strategies for the TPC becomes a complex issue. This paper presents the small signal modeling of the isolated TPC with proper decoupled networks to eliminate the interaction between multiple power control loops. The decoupled network allows a closed loop power control system design for the TPC to control the port powers independently. As two degrees of freedom (DOFs) are available, the control system can control the PV port power and the ac load port power. The battery port must then provide the balancing power. The power flows between the ports are managed by phase shift modulation (PSM). The responses of the power control system of the proposed TPC with decoupled networks are verified by simulation studies.

According to the perfect lens theory, wireless power transfer (WPT) efficiency can be improved significantly by positioning a magnetic metamaterial (MM) slab with effective permeability of −1 between a transmitter and receiver. However, it is not practically preferred because the actual space between the transmitter and the receiver will be compromised by the existence of the MM slab. In this paper, we propose to place an anisotropic MM (AMM) slab to back the transmitter coil, which can enhance the WPT by modulating magnetostatic volume wave resonant modes within the slab, and more importantly avoid the obstruction of the transfer space by the slab. Both simulations and experiments verified this enhancement due to the Fabry-Perot-like (FPL) resonances of the magnetostatic volume waves (MVWs), which increases the magnetic field intensity and eventually the inductance of WPT. Influences of key variables such as the MM slab dimensions on the induction of WPT are further investigated.

Energy storage systems (ESSs) are of crucial importance in electric vehicles (EVs). Batteries as the best existing storage solution have been used widely in EV applications. ESSs based on batteries are simple but have several challenges. Main issue of them is that the power density of batteries is not high enough to meet the high power demands of EVs. Hybrid energy storage systems (HESSs) consisting of batteries and ultra-capacitors are proposed to mitigate this issue. In this paper effective utilization of stored energy of UCs as a main challenge in designing HESSs is introduced and a novel solution is proposed.

Behaviour-based distributed energy management for charging electric vehicles (EVs) in photovoltaic (PV) charging station (CS) has been introduced in this paper. Based on the provider or consumer of the power, CS and EVs are modeled as independent players with different preferences. The energy distribution problem is modeled as a noncooperative stackelberg game and the existence of equilibrium among players is proofed at each control instant. Update of Charging powers of EVs in a distributed fashion is implemented through utilising the learning-based consensus network. Static and dynamic analyses are shown in simulation. Moreover, different behaviours of the EVs' drivers to the discount on the power price offered by the station is also showed. All the previous results proof the effectiveness and workability of the proposed energy management.
