PhD Overview
• Focus on residentialdwellings
• Aim to implement afeasible, economicand powerful DSMresidential system
What is DSM and DR?
• Demand side management (DSM) can be described as the concept of altering the pattern of a customer's electricity use "behind-the-meter” .
• Similarly, demand response (DR) is often described as the change in electric usage by end-use customers from their normal consumption patterns in response to changes in the price of electricity over time, or to incentive payments .
DSM - Measures to balance the supply/demand
Peak Clipping Reduction of load during peak demand periodsValley-Filling Improvement of system load factor by off-peak load buildingConservation Reduction of utility loads by efficiency measures
Flexible Load Shape Programs aimed at altering customer consumption by interruptible/curtailable agreements
Load Building Increase of utility loads Load Shifting Reduction of peak demand load, while increasing off-peak load

Context and Motivation
Grid supply and demand mismatches Balancing large-scale generation against variable system demand profileIncreased contribution from wind generation
On-going developments include:Communications technology Building energy management systemsRollout of smart metering Home area networks Time of day / real-time electricity pricing
Past assumptions of largely uncontrollable load likely to change
Increased renewables penetration system flexibility challenges
Example
Research Question:
Can DR algorithms be effectively used in residential buildings ?
Objectives of the PhD
oEvaluate the flexibility of demand response strategies in all-electric residential building using building simulation analysis
oDevelop demand response algorithms for implementation on Home Area Network systems
oTest and optimise demand response algorithms on a low energy all-electric test residential dwelling

Preliminary results – Economic performances
Preliminary ResultsCO2 emission: days with different wind penetration
CO2 emissions for two days with different wind penetration:
• Low wind at 4%
• High wind at 20%
Preliminary Results – Load Shifting from SMP peak

Future Work Develop control algorithms for demand
response management of residential energy systems.
Evaluate and optimise demand response algorithms in the test bed house
Assess performance (i.e., energy use, energy cost, thermal comfort, occupant response, system flexibility, etc.).
The Vision!
2014• System
developed and tested
2015• End of PhD
2025• Every
residential house will have an energy management system EMS based on HAN
2030• Aggregators
use the EMS to balance supply demand of energy
• RES penetration more than 50%
