  1. 1. Big Data als innovatie PDMA Masterclass Big data @CISCO - Amsterdam Jurjen Helmus University of Applied Sciences Amsterdam Innoveren met Big dataOF

  3. 3. First remark Deze presentatie is deels gebaseerd op onderstaand artikel, verkrijgbaar voor leden op de PDMA.nl website
  4. 4. Second remark balans te zoeken tussen complexiteit en for dummies Geef dus vooral aan als iets te eenvoudig/bekend is
  5. 5. 5 Part 1: Wat is big data NIET
  6. 6. (op en vraag die niet gesteld is) Big Data is niet het antwoord
  7. 7. Big Data is niet direct innovatie (maar kan er wel toe leiden)
  8. 8. Big Data is niet één specifieke nieuwe methode (maar een paraplu)
  9. 9. Big Data is in essentie niet nieuw (maar een samen gang van 4 werelden) 1. Data Generatie – Sensoren, web2.0, machine data, 2. Data opslag en werking – naast SQL ook NOSQL (non-structured) data opslag, streaming data, meta data 3. Data analyse – sneller, complexer, beter maar vooral machine learning (80’s) en deep learning 4. Data visualisatie – sneller, flexibeler, intuïtiever Data Generatie Opslag en verwerking Statistische analyse visualisatie Bron: Gartner.com

  21. 21. Our dataset consists of >715,000 charge sessions from charge point operators in 4 largest cities Parameter Example Explanation Charge point address Admiralengracht 44 Adress of the charge point Charge point operator Nuon Owner of the charge point Charging service provider Essent Owner of the used charging card Charge point city Amsterdam Charge point postal code 1057EW ZIP code of the area of the charge point Volume 0,86 Charged energy [kWh] Connection time 0:14:23 Time the car was connected Start Date 18-04-2012 Date the session started End Date 18-04-2012 Date the session ended Start Time 23:20:55 Time the session started End Time 23:35:18 Time the session ended Charging time 0:14:23 Time the car is actually charging RFID 60DF4D78 RFID code of a charging card Charge volume Charge point address Connection time RFID The data is enriched with information from the municipality and Dutch Statistics Agency (CBS) such as parking zones, neighborhoods, demographic & social information

  23. 23. Klantgedrag kan wiskundig beschreven worden waaruit middels cluster analyse klantgroepen ontstaan Sign Explanation Start time Mean and standard deviation of the start time of first charge session of the pattern. This is measured at the left side of the pattern, see Figure 5. End time Mean and standard deviation of the end time of last charge session of the pattern. This is measured at the right side of the pattern see Figure 5. Duration Mean and standard deviation of the connection time. TBSweekdays Mean and standard deviation of time between two charge sessions during weekdays. TBSweekends Mean and standard deviation of time between two charge sessions during weekdays. kWh Two types of parameters are taken into account. The mean and deviation of the kWh charged; and the mean and standard deviation of kWh charged divided by largest charge session over all charge sessions. The latter discounts the effect of the car type. Charging point volatility Variability of amount of charging points per charge session corrected by available charging points per session. This parameter is used both absolute as well as relative. Absolute is the mean amount of charging points user per charge session. Relative takes into account the relevant available charging points per session for the specific EV user. Time Ratio Mean and standard deviation of the charging time divided by connection time C,L,kWh Correlation between the time between two charge sessions and the amount of charged kWh of the last session. For this parameter 0 is no correlation and 1 is maximum correlation. C,S,TR Correlation between time ratio and start time of last session. For this parameter 0 is no correlation and 1 is maximum correlation. Pattern type Type of pattern as displayed in example figures. The pattern is formed by the percentage of total of connection hours per hour of the day Overzicht meetbaarheid gebruikersgedrag in

  26. 26. Voorbeeld de time Ratio is a leidende factor for V2X applicatie Note: 1. In Amsterdam the non-smart charging points directly start charging after connection 2. Slack exists only after charging is finished while connection remains 3. To identify max battery capacity the data requires 1 time ratio 100% session and 1 << 100% session The time ratio is defined as the charge time divided by the connection time
  27. 27. Time Ratio is a leading factor for V2X applications The time ratio is defined as the charge time divided by the connection time Slack Note: 1. Sessions with time ratio <<100% are best usable for V2X applications 2. Sessions with time ratio of 100% are not useful for V2X, these mostly occur at car sharing session No slack for power delivery/ postponing or slower charging, low V2X potential Slack for other charging modalities, thus high V2X potential

  30. 30. Similar clusters were found for mean potential kWh at start of session Map of Amsterdam with mean potential kWh at start of session per user Source: CHIEF database
  31. 31. Local mean time ratio displays a different pattern Map of Amsterdam with mean time ratio per user Low mean time ratios occur at different places than the previous slides display Source: CHIEF databaseNote: a slightly different dataset was used due required to calculate the time ratio
