1. Talents of tomorrow: Grid integration

2. Impact of using public network communication infrastructure for voltage control coordination in smart grid scenario
Pitch by Kamal Shahid, PhD Fellow, Aalborg University This work illustrates the impact of changing ICT properties on online voltage control support and coordination of renewable generation plants (WPP, PVP) in medium voltage distribution systems. More specifically, this work focuses on the existing public network communication infrastructure to show how time-varying delays, for instance, caused by link failures and cyber-attacks, can affect system’s performance. The main outcome of this study is to provide a generic overview of the aspects and their effects related to the use of existing public network communication infrastructure for online coordination of voltage control in a distributed system, considering the huge ReGen penetration, in order to ensure a resilient voltage controlled distributed systems.

3. A tool for optimal congestion management in distribution networks with large penetration of distributed energy resources
Pitch by Panagiotis Pediaditis, MSc, DTU Wind Energy The congestion management tool gives businesses, that own and/or manage Distributed Energy Recourses (DERs), such as Wind, PV, EVs, Heat Pumps, etc., the ability to cooperate with the Distribution System Operator (DSO), in order to obtain the optimal biding schedule for the Day-Ahead (DA) market that is free of network problems. The method considers both voltage and line problems, both consuming and generating DERS, and requires no exchange of private or sensitive information as it is based on a distributed algorithm. The method can greatly increase social welfare by eliminating unnecessary curtailment of generation and consumption.

4. Advanced Active Power and Frequency Control of Wind Power Plants
Pitch by Claudiu Ionita, MSc EE, Vattenfall This project deals with the design and tuning of a wind farm controller, with focus on the active power and frequency control. The validation of the controller algorithm is made using a Real-Time Hardware in the Loop approach using an industrial controller and a simulation platform provided by OPAL-RT. The robustness of the controller and disturbance rejection capability has been verified successfully for different operating conditions using the model of a 160 MW wind farm, containing 80 wind turbines. The outcome of this project is a stepwise method to design and tune the active power controller.

5. Cost-optimal design of a simplified highly renewable Chinese electricity network
Pitch by Hailiang Liu, PhD Fellow, Aarhus University Rapid economic growth in China has led to an increasing energy demand in the country. In combination with China's emission control and clean air initiatives, it has resulted in large-scale expansion of the leading renewable energy technologies wind and solar power. Their intermittent nature and uneven geographic distribution, however, raises the question of how to best exploit them in a future sustainable electricity system where their combined production may very well exceed that of all other technologies. It is well known that interconnecting distant regions provides more favorable production patterns from wind and solar. On the other hand, long-distance connections challenge traditional local energy autonomy. In this paper, the advantage of interconnecting the contiguous provinces of China is quantized. To this end, two different methodologies are introduced. The first aims at gradually increasing heterogeneity that is non-local wind and solar power production, to minimize production costs without regard to the match between production and demand. The second method optimizes the trade- o_ between low cost production and high utility value of the energy. In both cases, the study of a 100% renewable Chinese electricity network is based on 8 years of high resolution hourly time series of wind and solar power generation and electricity demand for each of the provinces. From the study we conclude that compared to homogeneously distributed renewable capacities, a heterogeneous network not only lowers capital investments but also reduces backup dispatches from thermal units. As an example, installing more capacity in provinces like Inner Mongolia, Jiangsu, Hainan and west-eastern regions, heterogeneous layouts may lower the levelized cost of electricity (LCOE) by up to 27%, and reduce backup needs by up to 64%.

6. Impacts of Climate Change on Future Wind-Dominated Energy Systems
Pitch by Smail Kozarcanin, PhD Fellow, Aarhus University Current research shows that anthropogenic climate change, already at present time, has strong impacts on natural and human systems but a limited amount of research concerns the impact on wind-dominated energy systems. In this work we explore the impact of climate change on highly weather dependent energy systems. We use 3 different projections of possible climatic outcomes during the 21. century. The projections are defined by the IPCC, and 3 hourly data on their consequences for the weather are available via the EURO-CORDEX project. Our research points towards an end-of-century period with dispatchable backup energy needs exceeding present day values. The demand for dispatchable energy happens to occur highly clustered which introduce challenges to the energy systems. Energy storage may be applied to handle the extreme energy demands. We present a simple theoretical modeling of energy storage to investigate this possibility.
