One of the most significant renewable resources is offshore wind (OSW) power that bears the capability to resolve the above discuss challenges, if developed properly. This paper is dedicated towards planned offshore grid development in the U.S. Atlantic Coast to integrate existing/future OSW wind power projects to the onshore grid. It proposes a modular multi-terminal HVDC (MTDC) network for large scale integration of OSW power. It addresses the associated challenges and provides a way forward for the realization of the planned offshore grid. This paper could provide an initial guideline for electric utilities, regulators, and government departments to accrue maximum benefit from the enormous OSW resource in the U.S.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"80 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132048742","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}

Current devices are designed to operate on 230 VAC. However, many of them include an AC/DC stage that incurs unnecessary losses. This paper investigates the power supply stages of several household appliances to determine their suitability to be supplied directly from a DC source. Three categories of home appliances were analysed: Switch Mode Power Supplies (SMPS), resistive heaters, and lighting equipment. Devices containing SMPS can operate on 325 VDC without any modification as most of their components are already rated for DC. Resistive heaters could work on 230 VDC with minor modifications as their contact switches are not rated for breaking DC currents. Appliances such as phase control circuits, direct-on-line induction machines and step-up/down transformers would need significant modification to operate on DC as these appliances rely on an AC supply to operate.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"45 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114500501","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 work proposes an innovative model-based method to minimize the electrochemical degradation of the Li-Ion cells. The method is applied in a Model Predictive Control (MPC), embedded in the microcontroller of the BMS. The MPC-based algorithm is maximizing the life of the cell’s digital-twin. This optimized management of the charging and discharging current, shows a reduction of the Solid Electrolyte Interface (SEI) growth by 30% to 40% and almost suppress the lithium plating compared with classical Constant-Current Constant-Voltage (CCCV) charging. As a conclusion, the new method promises longer use of the lithium batteries, especially for the energy storage in the modern and future Power Grids and Microgrids.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"72 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124905494","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}

The proposed control strategy effectively utilizes the ability of the battery storage devices to provide/absorb active power during the period of power deficit/excess. The controller uses the consensus based approach for distributed frequency control. The consensus is achieved in finite time where each of the node shares its local information such as the battery energy and battery power with its neighbours. The conventional PI controller uses as the main controller for the LFC with the combination of state feed back loop within the multi-agent control framework. A number of numerical examples are taken into account during simulations to show the usefulness of the suggested controller. The results indicates better performances of the proposed system over conventional LFC.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"70 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123555919","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}

The scheme being developed uses a Kaplan reaction turbine at a design head of around 2.5 m. A test rig has been built for turbine development; this enables empirical data to be gathered to optimise the mechanical efficiency of the design and determine optimal operating conditions. Power is generated using an induction motor. A Chroma grid simulator has been used to provide the inductive machine’s reactive power and absorb the real power generated during testing. The final scheme will experience variation from both the input power and the village load requirements. Therefore, load control and reactive power control are being developed.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123245827","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}

Among all load forecasting tasks, high granularity cases, i.e., industrial and residential level are acknowledged much more challenging than the aggregated forecast. Heterogeneous high granularity loads with different patterns make the performance of load forecasting frameworks volatile, which brings difficulty for model design and model selection. To this end, we explore the predictability for different loads in terms of various indicators. Specifically, we measure the predictability for various electric loads from internal load structure and external prediction accuracy using different forecasting models. We further adopt the notion of job-housing ratio and construct synthetic data using various loads with predefined portions to simulate electric loads for different job-housing cases, which provide a new perspective to study the load predictability of the transformed power systems under accelerated urbanization process. Numerical study shows that different electric loads have various degrees of predictability. Meanwhile, job-housing ratios make a significant difference in the performance of prediction models and the effects on the predictability are quite varied when combining different industry loads.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125577943","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}

If a short circuit fault occurs in DC microgrids, the contribution of multiple sources including main grid and DC sources might lead to very high fault levels that are difficult to break. While technologies for manufacturing the DC circuit breaker with higher breaking capacity are on-going, another approach by changing tripping sequences in DC protection systems, which could reduce fault currents to be interrupted by a single circuit breaker, was studied in this paper. With the aid of MATLAB/Simulink and OPAL-RT 5700 real time simulation, effectiveness of the proposed approach was evaluated on a Simulink stimulation model of 500 V, 1 MWgrid-connected DC Microgrid. The result obtained indicated that the fault current level interrupted by the DC circuit breakers was reduced by up to 63%.","PeriodicalId":421600,"journal":{"name":"2022 7th IEEE Workshop on the Electronic Grid (eGRID)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124383953","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}

Such new components include storage systems, distributed generations, which are also referred to as the negative loads; we regard all these new components the dispatchable load. Specifically, since the costs for these dispatchable loads to respond to load shedding requests are different, we regard such costs as the quality of services requirements of the dispatchable loads, and we are interested in how to identify the market power in a market with heterogeneous dispatchable loads. We construct functional measures to understand the influence of different parameters on market power.
