“…Distortions can have a transient characteristic, for example, in the turning on or off of loads or generators, or be constant at steady state, for instance, due to the operation of non-linear loads or power electronic interfaced generation [58]. Energy storage has been investigated for this application, and it has been proved an effective solution [59], [60].…”

Recent developments in the electricity sector encourage a high penetration of Renewable Energy Sources (RES). In addition, European policies are pushing for mass deployment of Electric Vehicles (EVs). Due to their non-controllable characteristics, these loads have brought new challenges in distribution networks, resulting in increased difficulty for Distribution System Operators (DSOs) to guarantee a safe and reliable operation of the grid. Battery Energy Storage Systems (BESSs) are promising solutions for mitigating the impact of the new loads and RES. In this paper, different aspects of the BESS's integration in distribution grids are reviewed. At first, the physical layer will be considered, focusing on the main battery technologies commercially available and on the power electronics converter. Secondly, the different functionalities that a grid-connected BESS can provide will be investigated, and then its sizing, location and control in distribution network will be discussed. In addition, an overview of actual BESSs installations is given. All in all, this paper aims at providing a comprehensive view of BESSs integration in distribution grids, highlighting the main focus, challenges, and research gaps for each one of these aspects.

“…1 Electrochemical capacitors are manufactured by several companies like Eaton Corporation PLC, Maxwell Technologies, and Skeleton Technologies, among others, simply as supercapacitors or ultracapacitors. Due to the aforementioned features, they are widely used in energy (like microgird stabilization) and transportation (like hybrid and utility vehicles) solutions either individually or in hybrid energy storage systems (ESS) 2 when coupled with a battery. The construction of an electrochemical capacitor typically consists of two current collectors, two facing electrodes dipped in an electrolyte solution, and a separator sandwiched between them to prevent short circuiting.…”

Monte Carlo‐based sensitivity analysis of an electrochemical capacitor

The operation of electrochemical capacitors depends not only on extrinsic operating and design parameters, but also intrinsic physical, material, and electrochemical parameters. Fluctuations in these stochastic parameters can significantly influence the performance and may lead to quicker degradation of the electrochemical capacitors, thereby affecting their durability and reliability. Thus, it is important to quantify the sensitivities of these extrinsic and intrinsic parameters and correlate them with the performance, to delay the inevitable performance degradation. To achieve this, we perform Monte Carlo simulations (MCS) followed by sensitivity analysis under high and low charge/ discharge current (load) conditions. The MCS is statistically performed by varying all the stochastic parameters simultaneously. We then identify the critical parameters that affect the performance under different load conditions, which provides insights into optimal operation of electrochemical capacitors. The thickness of positive electrode and the radius of active material were identified as the most significant parameters under low and high load conditions, respectively. Furthermore, we derive reduced order surrogate models with at least 95% accuracy using supervised machine learning techniques to predict the performance without solving the full physics-based model.

“…This scheme takes the dynamic pricing of grid power into account but doesn't consider the islanded operation of microgrid which is very frequent in residential power sector. In [3], an EMS is proposed which injects!consumes power from grid according to DC and AC load changes and RES power changes. But the excess power mode in which the grid is absent and ESS has fully charged is not considered.…”

Ahstract-This paper proposes a new architecture for a res idential microgrid with h y brid energ y storage s y stem and a control algorithm to integrate it with utilit y grid. The proposed architecture has multiple DC outputs and an AC output to feed various DC and AC loads in the microgrid. This architecture with proposed control algorithm achieves continuous and reliable power suppl y to local loads in a residential microgrid and ex port/import power to/from grid. The proposed control algorithm considers the PV variations, grid availabilit y and variations in local loads. In the proposed s y stem multiple dc outputs i.e 200V and 48V dc are emplo y ed to suppl y high power DC loads and criticaillow power DC loads respectivel y . The control algorithm alwa y s maintains the 48V DC bus on, so that the criticalllow power DC loads in the microgrid are continuousl y supplied power. A single phase voltage source converter(VSC) transfers real power between DC grid and utilit y grid and supplies power to local AC loads. It also provides ancillar y services such as reactive power support and unit y power factor and harmonic mitigation at the point of common coupling (PC C).Index Terms-Batter y , supercapacitor, grid integration, h y brid energ y storage s y stem, Power management, Photo voltaic power generation. I. IN TRO DUCTIONThe ever increasing demand for energy efficient appliances is promoting DC appliances in residential and commercial power sectors. DC appliances like LED lighting, inverter driven appliances like refrigerators and air conditioners are gaining popularity. So, both AC loads and DC loads will co-exist in residential power sector. At the same time, the renewable energy based distributed generation is spreading rapidly because of the new barriers set by environmental and economical issues faced in modern power system.The intermittent nature of renewable energy sources is a bottleneck for it's proliferation. In a microgrid system, meeting the load demand by maintaining the energy storage system's state of charge (SoC) within limits is an exigent task due to the uncertainties in renewable energy source (RES) power. So, the control algorithm plays a vital role in reliable and continuous operation of micro grid. Generally, battery energy storage systems (BESS) are predominantly used in microgrids. They have high energy density but low power density and suffer from low life time [1]. In contrary supercapacitors have high power density but low energy density. Hence, a unique combination of battery and supercapacitor based hybrid energy storage systems (HESS) can offer high power density as well as energy density. In HESS, supercapacitor supplies peak power while battery supplies average power. It increases the lifetime of battery by elfectively diverting high frequency disturbances in the system to suspercapacitors [1].978-1-4673-6540-6/15/$31.00 © 2015 IEEE A significant work on grid interactive micro grid with HESS can be seen in [2]-[10]. In [2] a unique control method is proposed for a grid interactive ...
