Year 2015Danish wind power generation: 42.1% of the electricity consumption

January 2014Danish wind power generation: 63.3% of the electricity consumption

December 21th 2013Danish wind power generation: 102% of the electricity consumption

Single hour July 9th 2015Danish wind power generation: 140% of the electricity consumption

March 11th 2014only 9 MW wind power generated out of installed 4,900 MW

but 480 MW out of 580 MW solar units supplied the grid

Takeaways1. Need of cutting-edge research to fulfill the vision of ”…the most

integrated, market-based and flexible energy system in Europe that can handle increasing volumes of renewable energy in a cost effective manner.”– Digital energy solutions– Integrated energy system– Optimized energy components

2. The energy system will be increasingly based on electricity, and new innovative solutions have to be found to efficiently handle high shares of fluctuating renewables– Balancing of demand-generation is the most widely addressed issue– Other stability mechanisms are equally important in a renewable-

based system, and new knowledge and tools have to be developed– Consumer and community based solutions plays an increasingly

important role, and may disrupt the whole business

The EcoGridMarket and Demand Response Performance

• Different response from customer group have to be taken into account in the market operation

• Response to prices with uncertainty• Activating demand reduces the peak load by

670 kW (corresponding to 27% flexibility)

• The societal costs from balancing are reduced by 5.4%

• The EcoGrid market allows to integrate 8.6% more wind power than the baseline market

Fast Real-Time Security Assessment of Power Systems with High Share of Renewables

Refs: IEEE Transactions on Power Systems, 2015Patent No. 111681113.6 – 2207, 2011

Conventional approaches• Off-line simulation-based analysis• Assessment times of 5 – 15 minutes• Insufficient for systems with high

share of stochastic energy sources• Detailed and accurate models needed

Developed approach• Analytical approach enables real-time assessment• PMU’s are an enabling technology• Assessment time 2.5 ms on laptop @ 7917 nodes,

1325 gens (Aperiodic small-signal rotor angle stability)• 2003 SW-DK blackout -> ≈80 s warning; no blackout• Optimal remedial actions can easily and fast be

identified

Digitalization and Sharing (Energy) Economy• Prosumer-centred electricity market

designs • Customer and community centred

energy sharing, e.g. peer-2-peer trading of energy services

• Enabled by blockchain technology
