To overcome this issue, in this paper, advanced power converters (multi-pulse AC–DC and multilevel DC–AC converter) are developed and implemented to feed vector-controlled induction motor drive (VCIMD), which enhance power quality of medium voltage drive system. Multi-winding transformers with multiphase conversion as well as phase displacement technique for multi-pulse AC–DC converters are designed. Hence, to attain high power quality at grid side, while drive system is designed with the few numbers of DC sources, a multiphase conversion and phase displacement techniques-based 50-pulse rectification system is designed and developed here. For it, circuit structure of five multi winding transformers (<i>T</i><sub><i>1</i></sub><i>, T</i><sub><i>2</i></sub><i>, T</i><sub><i>3</i></sub><i>, T</i><sub><i>4</i></sub><i>, T</i><sub><i>5</i></sub>) is developed through phase displacement and multiphase conversion (3- phase to 5-phase) technique instead utilising low reliability components. Apart from this, to overcome the challenges at the drive side, a six-level cascaded multilevel inverter is developed with a low number of components. The rigorous design of a 50-pulse AC–DC converter and six-level cascaded inverter-based medium voltage drive system is made and responses of this system are analysed through experiments (7.5 kW IM) at various operating conditions. In verification processes, operation principle and impact of converters utilisation are clearly analysed. More importantly, using proposed circuitry, the input current is almost sinusoidal; its input current total harmonic distortion is less than 5%.

This variability and time delay from decentralised control configurations can impair load frequency control (LFC) and compromise system stability. This study proposes a robust adaptive integral terminal sliding mode controller (RAITSMC) for LFC to address these challenges. The controller mitigates destabilising effects from time delays, parametric uncertainties and nonlinear disturbances. A delay-dependent sliding surface is developed to enhance the system's response to tie-line power and frequency deviations. Perturbations are estimated using an adaptation law, and a decentralised robust control law ensures the system's trajectory remains on the sliding surface with minimal control efforts. The controller's stability is validated via the Lyapunov theorem, and its parameters are optimised using the arithmetic optimisation algorithm.

Battery energy storage systems (BESS) have attracted much attention in providing frequency control ancillary services (FCAS), as they provide flexibility to store and release energy when required. With a larger inverter size and energy capacity, BESS can provide more frequency support to the grid but will incur large capital costs. Thus, it is important to minimise the size of the battery while ensuring system security requirements are fulfilled. In this paper, a large-scale BESS sizing framework is developed to obtain the optimal battery inverter size and energy capacity. The proposed framework determines the battery size based on two aspects: (i) contingency frequency control ancillary services (C-FCAS) to provide primary frequency support after a generator outage event and (ii) regulating frequency control ancillary service (R-FCAS) to match the power imbalance caused by the normal variation of load demand and RES generation. This paper also investigates the highest RES penetration level and the largest number of synchronous generators (SGs) that can be simultaneously reduced as the share of RESs increases. The effectiveness of the developed large-scale BESS sizing framework is tested on the Alice Springs power grid in Northern Territory, Australia. According to the study, the FCAS battery designed based on the proposed framework can fulfil the frequency support requirements under high solar-PV penetration in the Alice Springs power grid while significantly reducing the dependency on synchronous generators.</p>","PeriodicalId":33288,"journal":{"name":"IET Energy Systems Integration","volume":"7 1","pages":""},"PeriodicalIF":1.6,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1049/esi2.70003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143784310","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Additionally, economic and technological issues further challenge widespread implementation of MTDC systems. The main constraints of MTDC protection coordination systems are generally associated with fault detection, DC reactor (DCR), DC circuit breaker (DCCB) operation time, and converter blocking time.

The system comprises of a power supply, voltage and current measurement capabilities at the power supply, and two levels of stray current measurements at each point. Data such as ambient temperature and humidity, current and voltage at the power supply, and voltage differentials between the railway tracks and the grounding structure are recorded using an Arduino Mega2560 microcontroller. It is hypothesised that stray currents, quantified as voltage differentials between the tracks and the grounding structure, vary in response to changes in load and environmental conditions. Experiments were conducted under various scenarios: variable load, constant load with rain, and constant load across different seasons. The results indicated that with a variable load, the voltage between the tracks increased. During constant load with rain, the average voltage between the tracks rose due to decreased insulation between the tracks and the grounding structure. Lastly, under constant load across different seasons, the most significant voltage change was observed during the rainy season. The findings demonstrate a significant correlation between these variables, with a pronounced influence of environmental conditions, particularly precipitation, on voltage fluctuations.

They also include predictive models for capacity decay in vanadium redox flow batteries, safety improvements through arc voltage and temperature analysis, and data-driven approaches for predicting the remaining useful life (RUL) of lithium-ion batteries (LIBs). Additionally, the articles explore lithium inventory estimation, surface modification of electrodes in zinc-bromine flow batteries (ZBFBs), and the impact of water on battery performance and safety.
