Demand response algorithms for Home Area Networks (HAN) Fabiano Pallonetto Supervised by Dr. Donal Finn and Dr. Simeon Oxizidis 17 May 2013
PhD Overview Focus on residential dwellings Aim to implement a feasible, economic and powerful DSM residential 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 ClippingReduction of load during peak demand periods Valley-FillingImprovement of system load factor by off-peak load building ConservationReduction of utility loads by efficiency measures Flexible Load ShapePrograms aimed at altering customer consumption by interruptible/curtailable agreements Load BuildingIncrease of utility loads Load ShiftingReduction of peak demand load, while increasing off-peak load [Gellings C.W 1985] Concept of demand-side management for electric utilities. Proc. IEEE.
Context and Motivation Grid supply and demand mismatches Balancing large-scale generation against variable system demand profile Increased contribution from wind generation On-going developments include: Communications technology Building energy management systems Rollout 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
Research Question: Can DR algorithms be effectively used in residential buildings ?
Objectives of the PhD o Evaluate the flexibility of demand response strategies in all-electric residential building using building simulation analysis o Develop demand response algorithms for implementation on Home Area Network systems o Test and optimise demand response algorithms on a low energy all-electric test residential dwelling
