1. Control of Big Data in the Smart Grid Luxin Zhang Dr. Eric Kerrigan and Prof. Bikash Pal Imperial College London UKACC PhD Presentation Showcase

2. Slide 2 Introduction   What is a smart grid?  Renewable energy;  Smart meters;

3. UKACC PhD Presentation Showcase Slide 3 Communication Scheduling Problem  Background and motivation for research  Existing algorithms often designed for multiprocessor systems;  Scheduling big data computing tasks in the data centres as well as homes, offices and factories in a smart grid.

4. UKACC PhD Presentation Showcase Slide 4 Communication Scheduling Problem  Objective: Minimising overall task completion time Subject to: Task load constraints; Operational frequency constraints; Transmission rates constraints; Task load balance constraints; NLP solver: Ipopt

5. UKACC PhD Presentation Showcase Slide 5 Conclusion and Future Work  The overall task completion time is reduced with communication control;  Investigate the inconsistencies of the solutions returned by Ipopt;  Add an energy consumption model;  Implement real-time streaming algorithms;
