Involving real-world speed data makes the prediction complex and dynamic. The stochastic nature of traffic makes predictions using traditional statistical methods unsatisfying in terms of accuracy and performance. Recently, deep learning methods have gained more attention to capture this chaotic characteristic. This study conducts an encoder-decoder sequence to sequence learning manner and WaveNet with a side information model and compares the results with Autoregressive Integrated Moving Average. Using Waze crowdsourced speed data collected from 31 segments of Interstate 40 (I-40) in Tennessee, the proposed algorithms are trained and tested for short- and long term speed prediction (time steps from 5-minutes to 2-hours). Our experimental results demonstrate the WaveNet model with side information achieves the best performance with MAPE 4.40% for 5-minuets and MAPE 5.58% for 2-hours prediction.","PeriodicalId":437709,"journal":{"name":"2020 IEEE Green Energy and Smart Systems Conference (IGESSC)","volume":"58 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116487720","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 Photovoltaic (PV) systems remain a dominant choice among other DERs and requires an inverter that historically exhibits non-linear characteristics. This criterion underscores the need for a comprehensive PV-inverter model and a sophisticated test bench for demonstrating the operational dynamics and protection functionalities of the system. Given this, a novel impedance-based mathematical modeling is proposed for the PV and inverter. The development of an advanced Hardware-in-the-Loop (HIL) testbed at SCE’s DER Laboratory has described interfaces commercial Rule 21 and IEEE 1547 compliant inverters with the traditional induction and synchronous generator based generations in Real Time Digital Simulator (RTDS) to replicate the simulated model of a medium voltage distribution circuit. Some preliminary simulation and experimentation results yield tremendous agreement and confirm the validity of the modeling approach. The future simulation and demonstration plans are exposed, which show the value of the model and testbed and this contributes evidence to other utilities to further model and develop a testbed for performance evaluations of DER systems.","PeriodicalId":437709,"journal":{"name":"2020 IEEE Green Energy and Smart Systems Conference (IGESSC)","volume":"34 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114751978","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}

However, to effectively operate the RE-based MEC system, a method for predicting the state of energy (SoE) in the battery is essential, not only to prevent the battery from over-charging or over-discharging, but also allowing the MEC applications to adjust their loads in advance based on the energy availability. In this work, we consider RE-powered MEC systems at the Road-side Unit (RSU) and focus on predicting its battery's SoE by using machine learning technique. We developed a real-world RE-powered RSU testbed consisting of edge computing devices, small cell base station, and solar as well as wind power generators. By operating RE-powered RSU for serving real-world computation task offloading demands, we collect the corresponding data sequences of battery's SoE and other observable parameters of the MEC systems that impact the SoE. Using a variant of Long Short-term Memory (LSTM) model with additional convolutional layers, we form a CNN-LSTM model which can predict the SoE accurately with very low prediction error. Our results show that CNN-LSTM outperforms other Recurrent Neural Networks (RNN) based models for predicting intra-hour and hour-ahead SoE.","PeriodicalId":437709,"journal":{"name":"2020 IEEE Green Energy and Smart Systems Conference (IGESSC)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-11-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126856304","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}

To this end, exchange market algorithm (EMA) is offered to find the optimal size and location of DGs subject to minimizing loss, increasing voltage profile, and improving voltage stability in the distribution systems.
