Environmental concerns and various benefits of small on-site generation have resulted in significant penetration of dispersed generation in many distribution systems. But, this has resulted in various operational problems. This course aims to address various challenges and opportunities with having a lot of dispersed generation in a network. It focuses on the balancing, stability and reliability problems in the network together with power quality. In addition, various aspects of islanded operation of distribution systems with dispersed generation are also discussed. The course also covers the role of electric vehicles and other flexible loads as a provider of ancillary services in the future electric power systems.

Day 1:

· Lecture 1: Energy Demand and Security of Power Supply (BBJ) (9.00-10.30)
The lecture introduces the trends of energy demand, relevance of dispersed generation, and challenges and solutions to security of future power systems.

· Lecture 2: Renewable Energy Sources and Storage Systems (FI) (10.45-12.00)
Different topologies of distributed energy resources, its characteristics and technologies are presented in the lecture.

· Lecture 3: Power Quality (BBJ) (13.00-16.00)
It includes various topics related to origin and consequences of various grid disturbances affecting power quality, and apparatus to compensate for the different disturbances.

Day 2:

· Lecture 4: Smart Grids (JRP) (9.00-10.30)
The trends and relevance of smart grids and smart energy systems, its architectures and importance of demand side management are covered in this lecture.

· Lecture 5: Grid Connection Requirements for Dispersed Generation (JRP) (10:45-12:00)
The various technical challenges and solutions to integrate DERs, grid codes for grid connection for various types of dispersed generation and storage units are presented.

· Lecture 6 – Flexible Demand and Ancillary Services (JRP) (13.00-16:00)
The lecture introduces the importance of ancillary services, need for alternative balancing reserves in renewable dominated power systems, application of flexible demand units (electric vehicles, heat pumps etc.) in power system operation and impact assessment of flexible demand units on distribution networks.

Day 3:

· Lecture 7: Grid Synchronisation and Island Detection (BBJ) (9.00-10.15)

Important information concerning PhD courses:
We have over some time experienced problems with no-show for both project and general courses. It has now reached a point where we are forced to take action. Therefore, the Doctoral School has decided to introduce a no-show fee of DKK 3.000 for each course where the student does not show up. Cancellations are accepted no later than 2 weeks before start of the course. Registered illness is of course an acceptable reason for not showing up on those days. Furthermore, all courses open for registration approximately four months before start. This can hopefully also provide new students a chance to register for courses during the year. 
We look forward to your registrations
