Faculty of Computer Science, Institute of Systems Architecture, T rustworthy and Energy-Effjcient Smart Grids Electric Intelligence: Concepts and features Joeffjson Silvério de Andrade Dresden, May 15, 2014

Electric-Load Intelligence (E-LI): Concept and Applications • Electric-Load Intelligence (E-LI)  develop new knowledge and apply it intelligently with technologies to enhance the value of electricity. - both intelligence gathering on electricity usages and smart applications of technologies to enhance the electricity services.  monitoring, communication, analysis, interface, decision making, control and learning capability TU Dresden, May 15, 2014 Revising 2 papers Folie 2 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Monitoring  Capturing and storing data (information about loads)  The applications may dictate the kind of data required and decisions to be made. [which.co.uk] TU Dresden, May 15, 2014 Revising 2 papers Folie 3 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Communication  transmission of data and/or controls among the stakeholders (customers, service providers, appliance manufacturers or even regulators) and associated devices. TU Dresden, May 15, 2014 Revising 2 papers Folie 4 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Analysis  consists on analyzing the data, deriving knowledge to suggest alternatives to better outcomes. TU Dresden, May 15, 2014 Revising 2 papers Folie 5 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Interface  The presentation of load data, analysis results, control alternatives and fjnal decisions to customers and service providers. TU Dresden, May 15, 2014 Revising 2 papers Folie 6 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Decision Making:  The decision taken after the outcome of analysis to achieve a prescribed objective - safety, effjciency, cost, etc TU Dresden, May 15, 2014 Revising 2 papers Folie 7 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Control  The instructions sent to devices/systems to improve performance or achieve desired outcomes. TU Dresden, May 15, 2014 Revising 2 papers Folie 8 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Learning  The ability of incorporating new knowledge into future analysis and decision making. TU Dresden, May 15, 2014 Revising 2 papers Folie 9 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Load Signatures Disaggregation  Disaggregation is to take a composite load and break it into a set of load signatures of identifjable devices. - Ability to track the usage and devise suitable optimization schemes to improve performance. TU Dresden, May 15, 2014 Revising 2 papers Folie 10 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Load Signatures Disaggregation  Optimization Problem Find the best "fjt" to a composite load with a set of given load signatures TU Dresden, May 15, 2014 Revising 2 papers Folie 11 von 20

Electric-Load Intelligence (E-LI): Concept and Applications • Applications Of Load Signature Studies  Information of detailed energy usage to help customers benefjt from time-of-use tarifg;  Health monitoring for mission critical, high value equipment or systems, e.g. in a data centers;  Facility management tools to provide energy savings in buildings;  Monitoring individuals or systems with specifjc needs based on their electricity usage patterns, e.g. senior living alone or remotely operated equipment;  Switching ofg non-essential loads (e.g. air-conditioners) in emergencies if the power system is in danger of collapse or breaking-up. TU Dresden, May 15, 2014 Revising 2 papers Folie 12 von 20

Load Signature Study—Part I: Basic Concept, Structure, and Methodology • Load Signature  The electrical behavior of an individual appliance when it is in operation TU Dresden, May 15, 2014 Revising 2 papers Folie 13 von 20

Load Signature Study—Part I: Basic Concept, Structure, and Methodology • Composite Load  CL is more complicated in nature because the unique features from individual appliances are mixed and sometimes certain features may even be masked or lost TU Dresden, May 15, 2014 Revising 2 papers Folie 14 von 20

Load Signature Study—Part I: Basic Concept, Structure, and Methodology • Micro Level  Any load collected using a sampling interval that is faster than 1 sample per cycle TU Dresden, May 15, 2014 Revising 2 papers Folie 15 von 20

Load Signature Study—Part I: Basic Concept, Structure, and Methodology • Macro Level  Any load collected by using a sampling interval that is slower than 1 sample per cycle TU Dresden, May 15, 2014 Revising 2 papers Folie 16 von 20

Load Signature Study—Part I: Basic Concept, Structure, and Methodology • Current Waveform  Provides one of the most complete sets of information to describe load behavior TU Dresden, May 15, 2014 Revising 2 papers Folie 17 von 20

Load Generator • Next steps  On the next versions of the tool, we want to include features/measurements useful for existent analysis Example TU Dresden, May 15, 2014 Revising 2 papers Folie 18 von 20
