The physical and statistical methods used to forecast mostly rely on meteorological information, site specific data and historical data from wind farms. Most of the existing works are limited to utilize single input data source and a prediction variable. However, some gap in using multiple data sources and multiple prediction variables as input has been identified to substantiate and enhance forecast accuracy of these models. In this paper, a multi-source and multivariate surveillance approach has been conducted using time series methods and machine learning algorithms. Firstly, the proposed model uses multiple sources to understand the deciding prediction variables. Secondly, an analogy among time series Autoregressive Integrated Moving Average (ARIMA), Recurrent Neural Networks (RNNs) with Long Short-term Memory units (LSTMs) is used. Although, the prediction models using single data source are economical for forecast providers and wind power producers considering multiple sources can certainly improve the forecasting accuracy thus reducing wind curtailments and imbalance penalties. A comparative approach has been made using data sources obtained for Gulf of Khambhat, a south to north penetration of the Arabian Sea on the western shelf of India. The obtained results show that the forecasting accuracy can be improved by considering multiple sources of input data.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123422688","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}

Since the meter clock is accessible only locally, the time drift can only be determined locally by visually comparing the time in the internal clock of the meter with the Indian standard time. Collection of information related to meter time drift every week from the locations where these meters are installed, is a cumbersome process and it is also prone to errors due to manual intervention in data collection. This paper shares the various techniques being applied presently for determination of time drift and proposes a novel application of cross correlation with linear interpolation (used in signal processing) for estimation of meter time drift at the data collection centre. The efficacy of the proposed method has been demonstrated with the help of simulations. The novel application has been successfully used in Western Regional Load Despatch Centre in India and is found to be accurate to +/−1 minute with a reasonable confidence level. The whole process of time drift estimation has been automated to significantly improve the energy meter asset administration.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"3 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124303255","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}

An operational criterion is developed for the microgrid to incorporate selective mode transfer in different scenarios. The grid isolation from the microgrid leads to shift in operating control scheme i.e. from current to voltage control for switching the grid connected converter. The isolation/reconnection of the utility to the microgrid takes place with the help of static transfer switches (STS) that operate on the detection/clearance of faults. The high quality power is ensured by utilizing normalized least mean square-sign error (NLMS-SE) algorithm to evaluate the total current active component of loads. All pass filter based frequency locked loop (APF-FLL) effectively estimates the phase angle of grid under phase and frequency oscillations prevailing in the system under synchronization. The proportional resonant (PR) controller regulate the load voltages during voltage control operating mode. The microgrid allows sensitive load operation, uninterrupted residential load supply and improved power quality and these are confirmed from MATLAB simulated results.","PeriodicalId":153735,"journal":{"name":"2021 9th IEEE International Conference on Power Systems (ICPS)","volume":"49 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125578699","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}
