“…A single-star bridge cell-based modular multi-level cascade converter with six bridge cells per phase is designed for the 500 kW/238 kWh BESS, which is stably connected to a 6.6 kV distribution line [71]. Single-stage converters generally provide the step-down function, which requires high rated switches and numerous series connected ESSs, thereby leading to negative effects such as decreased BESS/UC lifetime, HF BESS/UC/SMESS current ripples, more electrolytic capacitors on the BESS side, lower system reliability and high system volume/weight [60][61][62][63][64][65][66][67][68][69][70][71].…”

“…Figure 2 presents a general block diagram of the AC bus PCS for the ESS. To ensure efficient interfacing with the grid, the AC bus PCS should have the capability of bidirectional power flow along with high efficiency, high power factor, good quality power conversion and low THD [55–72]. The AC bus PCSs can be divided into two categories based on the architecture: a two‐stage architecture with a cascaded DC/DC converter [55–59] and a quasi‐single‐stage architecture with an embedded DC/DC converter [60–72].…”

“…This paper provides critical insights by filling the gap about the advancements of the power converter topologies and their control techniques in the PCS employed for BESS, FESS, SC/UC and SMESS in the power system applications. Generally, the PCS of ESSs consists of a combination of power converters, that is, DC/DC, DC/AC, AC/DC and AC/AC converters [20–72]. With the improvements in the power semi‐conductor switches with a wide band gap (WBG), many topologies of the PCS are now available with reduced total harmonic distortion (THD), smooth output voltage and high efficiency.…”

Energy storage systems are pivotal for maximising the utilisation of renewable energy sources for smart grid and microgrid systems. Among the ongoing advancements in energy storage systems, the power conditioning systems for energy storage systems represent an area that can be significantly improved by using advanced power electronics converter designs and control techniques. Normally, the battery, flywheel, ultracapacitor and superconducting magnetic energy storage are the types of energy storage systems that typically require power conditioning systems for efficient bidirectional power flows. Compared to the previous review papers, this paper critically reviews the power conditioning system configurations and control techniques from the perspective of energy storage system applications in the power systems. First, the power conditioning systems are categorised into DC bus power conditioning systems and AC bus power conditioning systems based on the output voltage types at the connected point. Next, the topologies and control configurations of popular power electronics are comparatively analysed to highlight their advantages and power system applications. Moreover, the control configurations are discussed in terms of the popular applications of energy storage systems, that is, power backup smoothing, frequency regulation, voltage regulation and power quality applications. In addition, the latest developments in the energy storage system such as multi-functional energy storage system stacking, artificial intelligence for power conditioning system of energy storage systems and security of control of energy storage systems are critically analysed. Finally, the review is concluded by discussing industrial applications and future research trends for the power conditioning systems of energy storage systems.

“…The efficiency of a solar array is also impacted by the compatibility of the different components, which make up the system. This includes the Power Conditioning System (PCS) which refers to devices that use power electronics technologies to convert electric power from one form to another as DC-DC and DC-AC converters [21]. PCS requires the input power to be around 30-50% of the rated power of the PCS to achieve anticipated rates of 94.5% in the DC-AC conversion process.…”

Semi-transparent Building Integrated Photovoltaics provide a fresh approach to the renewable energy sector, combining the potential of energy generation with aesthetically pleasing, multi-functional building components. Employing a range of technologies, they can be integrated into the envelope of the building in different ways, for instance, as a key element of the roofing or façade in urban areas. Energy performance, measured by their ability to produce electrical power, at the same time as delivering thermal and optical efficiencies, is not only impacted by the system properties, but also by a variety of climatic and environmental factors. The analytical framework laid out in this paper can be employed to critically analyse the most efficient solution for a specific location; however, it is not always possible to mitigate energy losses, using commercially available materials. For this reason, a brief overview of new concept devices is provided, outlining the way in which they mitigate energy losses and providing innovative solutions for a sustainable energy future.

Z and quasi-Z-source inverters (Z/qZSI) have a nonlinear impedance network on their dc side, which allows the system to behave as a buck–boost converter in their outputs. The challenges derived from the qZSI topology include (a) the control of the voltage and current on its nonlinear impedance network, (b) the dynamic coupling between the ac and dc variables, and (c) the fact that a unique set of switches are used to manage the power at dc and ac side of the system. In this work, a control scheme that combines a PWM linear control strategy and a strategy based on finite control state model predictive control (FCS-MPC) is proposed. The linear approach works during steady state, while the FCS-MPC works during transient states, either in the start-up of the converter or during sudden reference changes. This work aims to show that the performance of this control proposal retains the best characteristics of both schemes, which allows it to achieve high-quality waveforms and error-free steady state, as well as a quick dynamic response during transients. The feasibility of the proposal is validated through experimental results.
