August 19th – 20th 2015
• Renewables, de-carbonisation of generation and demand
– Renewables massively distributed– System will behave completely differently in future

&L&8* Data from 1989/1990 to 2003/2004 indicates collaborative spending on R&D amonsgt the DNOs * IFI data represents the total R&D spend by all DNOs up to the last financial year
* Data from 1989/1990 to 2003/2004 is the collaborative spending on R&D amongst the DNOs through a single provider.* Data from Oct 2004 - April 2005 and the last financial year (2005/2006) shows reported total IFI spend.

Challenges
August 19th – 20th 2015
Solutions – selected UK projects (Strathclyde)
• C2C (Capacity to Customers) – increase asset utilisation, defer and reduce reinforcement - load shedding and network reconfiguration following faults (Electricity North West)
• SFC (Smart Frequency Control) – use of PMUs, fast control and communications to rapidly control resources (generation and load) to provide support to system during transients
• ACCEPT – (Advanced Communication and Control for the Prevention of Blackouts) – development of “defensive” strategies to reduce risk of blackout –load/generation management, separation of system into islands…
August 19th – 20th 2015
Facilities to investigate, demonstrate and test solutions

• This is only the beginning – PNDC is flexible• We will react to industry, government and academic
requirements - work with us
EAST!
We are still learning….
August 19th – 20th 2015
• Opportunity to define a true “smart” and “future-ready” power system in Malawi
– Collection of “microgrids” - grid-interconnected,-but could be split in “defence” mode?
– Control and operation – “smart” functions?– Role of DC?– Role of energy storage? – Sensing, communications?
• Share in UK experience: exchange knowledge, innovate and demonstrate potential solutions through partnerships
• Education and research:– Our Centres for Doctoral Training are available now
