The model uses simulated power data to operate an energy management system (EMS) with shore power and a port energy storage system (ESS) for a green port. Based on the calculated electricity costs, the optimal power output of the energy management system is established such as the rating of the power sources and sizing of the ESS. In the next step, the model is used for system optimization of operating expenses and to improve the availability of the onshore supply system by adjusting the energy sources based on the renewable energy sources (RES) available and the state of charge of the on-shore battery. Finally, the optimal power output profiles of an EMS change based on the availability of RES generation during a sunny and cloudy day. Further, this integrated energy system can be adapted for future green ports supplying multiple vessels with various energy sources such as Liquefied Natural Gas (LNG), ammonia, and hydrogen.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"18 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81725667","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel approach to modeling the power consumption of trams is presented in this paper. To identify the unknown parameters influencing the rolling resistance force acting on the tram, it is necessary to measure the power consumption and speed of a single tram (or multiple trams if there are different car types in operation). The developed model of the tram is calibrated with data from the Sarajevo tram system. Simulation results are compared with measurements and a good correlation was obtained. The power consumption model of the tram with identified parameters can be further used to develop a framework for the power consumption estimation of the traction substation.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"6 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73940608","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

For the 3-phase Voltage Source Rectifier (VSR), as switching frequency increases, the DC-link capacitor may be reduce while maintaining the same voltage ripple. However, an often overlooked part in sizing the DC-link capacitance is the converter's stability. The use of conventional control methods, such PI-based controls, may lead to larger DC-link capacitance to prevent instability, minimizing the value proposition of Wide Band Gap-based power conversion. Applications like electrified shipboard or more electrical aircraft can be extremely sensitive to increases in size/weight due to limited space and/or significant annualized fuel costs. To this end, this paper explores, through simulation, a nonlinear control method based on Lyapunov's direct method published 25 years ago to minimize DC-link capacitance of an SiC-based VSR.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"58 1","pages":"1-7"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74029047","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This aspect represents a challenge when focusing on the dynamics performance in balancing the power flows and when considering the large amount of energy to be managed. To this issue, the DC technology is an effective solution to prioritize the flexibility of shipboard power systems and for a better use of onboard energy. A DC shipboard microgrid is a complex system, incorporating several controlled converters. Between the main priorities, certainly the system stability has a prominent role. Indeed, unstable interactions among controlled converters and their filtering stages can arise during the ship operation, thus eventually compromising the ship mission. As the analytical stability assessment on this controlled system is not feasible, then equivalent models or order reductions help when investigating on stability performance. In this work, a cascade-connected shipboard DC system is studied, and an analytical expression of its stability boundaries is attained. The stability results are verified by means of circuital simulations to identify when the load filters are negligible, then achieving the chased order reduction.","PeriodicalId":38493,"journal":{"name":"AUS","volume":"32 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2023-03-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75216014","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In such scenario, local renewable energy sources, energy storage systems, smart appliances and EVs charging points can be managed in a smart way, with the aim to minimize the stress on the distribution grid given by the stochastic and intermittent behaviour of the aggregated demand. This paper presents a study focused on the energy flow optimization of a smart home equipped with a bidirectional EV charging wallbox, a local energy storage system (ESS) and two deferrable appliances (DAs).
