Electric Intelligence: Concepts and features

TU Dresden, May 15, 2014 Revising 2 papers Folie 2 von 20

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 3 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.

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 5 von 20

Electric-Load Intelligence (E-LI): Concept and Applications

• Analysis
• consists on analyzing the data, deriving

knowledge to suggest alternatives to better

• utcomes.

TU Dresden, May 15, 2014 Revising 2 papers Folie 6 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 7 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 8 von 20

Electric-Load Intelligence (E-LI): Concept and Applications

• Control
• The instructions sent to devices/systems to

improve performance or achieve desired

• utcomes.

TU Dresden, May 15, 2014 Revising 2 papers Folie 9 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 10 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 11 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 12 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.

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 14 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 15 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 16 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 17 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 18 von 20

Load Generator

• Next steps
• On the next versions of the tool, we want to include

features/measurements useful for existent analysis

Example
