One way of addressing this issue is Virtual Power Plants (VPPs), which aggregate a diverse set of DER to act in various electricity markets as a single entity. This work introduces a modelling framework which allows a VPP to operate in multiple markets, considers multiple energy vectors, and dispatches devices at 5-minute intervals, while operating within local network constraints. To ensure framework tractability, it is divided into a three-stage optimization: the high-level scheduling the devices; the mid-level dispatching them with 30-minute timesteps over a 24-hour horizon; the low-level performing the 5-minute dispatch. A real case study with electricity and hydrogen in South Australia is conducted. Results show the VPP coordinating renewable generation, dispatchable load, hydrogen storage and thermal generation to maximize earnings over multiple markets whilst adhering to local network constraints.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130158381","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}

Algorithm ensures that windings temperature and loss of insulation life do not exceed their permissible limits. To achieve this goal, we use receding horizon control. Receding horizon control considers load and ambient temperature at past and future intervals to update the DTR. Proposed algorithm is intended for application in real-time economic dispatch at balancing market where it could allow the decreasing of energy generation cost. We consider a two-machine power system as case study, where cheap generation is constrained by transformer rating. The expensive generation does not have any network constraints. The algorithm application increased the cheap generation by 12% in comparison with static thermal limit and by 3% in comparison with static thermal limit corrected to ambient temperature. The generation rescheduling, allowed by DTR, decreased the energy generation cost by 27.9% and 9.8% correspondingly.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122029781","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 simple, linear transfer function model is built using collected ring-down measurements to capture the system’s oscillatory behavior. This constructed transfer function model is utilized for the controller design, instead of a complicated dynamic grid model. A measurement-driven approach is used to tune the parameters of the controller, thus the transfer function model can be updated online to track the variations of the system operating condition. The proposed approach is validated through a case study on the Italian power grid. The optimal observation signal for the controller is selected using Fast Fourier Transform (FFT) analysis of ring-down measurements. Two Compensation Devices (CDs) are selected as the actuators for the WADC. The control effect of the designed controller is shown for an actual undamped oscillation event that took place in December 2017.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127650732","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 applied method is based on the calculation of the conductor surface voltage gradients considering the interaction between AC and DC circuits. Then, the radio interference levels produced by each phase/pole conductor are calculated by means of empirical formulas presented in previous works for two weather conditions: heavy rain and fair weather. Two hybrid line configurations are compared in order to determine which one produces the lowest RI levels. After that, vector optimization is applied in order to minimize the RI levels produced by the best hybrid line configuration, considering three independent variables: subconductors radius, bundle spacing, and the number of subconductors in the bundle. Finally, RI lateral profiles with both nominal and optimal values are compared.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"2013 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127302702","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 two-stage model features a here-and-now framework for shaping the aggregated demands during operation. First, the day-ahead scheduling problem is solved by adopting Unit Commitment (UC) to determine the generation level of power generation units as well as the Locational Marginal Prices (LMPs). Afterwards, the obtained LMPs are considered as the Time of Use (ToU) for the second step of the scheduling and reshaping the demanded loads of each aggregator. A new methodology is provided in this paper to estimate the reaction of consumers behavior in terms of encouraging their participation in DRPs. Unlike classical models which adopt load reduction over the operational horizon, this model ensures that the total demanded loads will be served. Therefore, the total supplied energy for the operational period before and after DRP implementation remains unchanged. Meanwhile, the total payment of consumers will be considerably reduced by adopting this strategy. The simulation results on the 6-bus test system clarify that the proposed model can reduce the total operational cost as well as smoothen the load profile and nodal prices over the operational horizon.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128348716","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 order to maintain the security of supply at the same level in the future, it must be ensured that wind and solar power plants are able to feed in electricity into the distribution grid without bottlenecks when activated. The present work presents a grid state assessment, which takes into account the special features of the control reserve supply. The identification of a future grid state, which is necessary for an ex ante evaluation, poses the challenge of forecasting loads. The Boundary Load Flow method takes load uncertainties into account and is used to estimate a possible interval for all grid parameters. Grid congestions can thus be detected preventively and suppliers of control reserve can be approved or excluded. A validation in combination with an exemplary application shows the feasibility of the overall methodology.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134125275","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 allows a more accurate consideration of transmission corridors carrying multiple parallel circuits, since expansion costs contain both circuit- and corridor-specific costs. Exemplary results show a significant impact of the detailed consideration of expansion costs on the identified expansion measures proving the necessity of a more detailed consideration of expansion costs.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133832830","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}

One of the main techniques for identifying incipient faults in these rotary machines is vibration-based condition monitoring. In this paper, the analysis is focused on squirrel-cage broken bars, a typical fault in induction motors. Using an experimental test rig in which this fault may be gradually introduced in a healthy motor, the paper shows how it changes the vibration pattern. This methodology, based on motor current signature analysis, originally developed for motor current analysis, was modified and applied to the mechanical vibration signals. It has shown itself effective for detecting faults when the motor load is 37.5% higher than the nominal value. Then this methodology was combined with Empirical Mode Decomposition to filter the signal and extract the intrinsic mode functions that contain fault’s characteristic-frequency components. This methodology successfully detected faults when the motor load was at 12.5%, that is the lower load tested, and with less sampling time. Besides that, the fault’s frequencies characteristics were found and demonstrated how important is the motor operation regime.","PeriodicalId":187144,"journal":{"name":"2019 IEEE Milan PowerTech","volume":"84 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114860937","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}
