Electricity Markets for Direct Current Distribution Systems

Direct current distribution systems (DCDS) are a promising alternative to alternating current (AC) systems because they remove AC--DC conversion between sources and loads that cause energy losses. Compared to AC systems, a DCDS has higher power capacity, energy efficiency and reliability, and no need for synchronisation---suitable where a large...

Coordination Strategies for Reducing Price Volatility in Local Electricity Markets

With increasing renewable energy and cross-sectoral electrification price volatility is increasing. Flexibility through demand-side management and electric storage has the potential for reducing price volatility. In this thesis, using duality theory the flexibility required for constraining price to a maximum limit is quantified. <br/...

Balancing and redispatch: the next stepping stones in European electricity market integration: Improving the market design and the efficiency of the procurement of balancing and redispatch services

Balancing and redispatch are essential services for the security and stability of the electricity network. Balancing refers to continuously maintaining a balance between supply and demand through activating flexible resources. Redispatch refers to changing the dispatch of generators to remedy network congestion. The need for flexibility...

Transmission Expansion Planning of Transnational Offshore Grids: A Techno-Economic and Legal Approach Case Study of the North Sea Offshore Grid

The new energy policy of the European Union (EU) with the core objectives of competitiveness, reliability and sustainability, has driven Europe into a transition towards a low carbon & sustainable electricity supply systems. Under the new policy, the European energy systems are pursing two major objectives. First is to shift the focus from...

Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources: Theory and Applications

Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. However, due to the deregulation of electricity markets and the growth in the share of power generation by uncontrollable renewable energies such as wind and solar, power system simulations are more...

Strategic Behavior in Liberalized Electricity Sectors: Game Theoretical Formal Modeling in Policy Analysis

The electricity infrastructure, like many other networked infrastructures, is an indispensable and integral part of developed economies. The economic growth, quality of life and general well-being of modern societies all depend on the smooth, reliable and efficient operation of electricity system. On the other hand, adverse strategic behavior by...

Designing Multinational Electricity Balancing Markets

In today’s unbundled electricity markets, the balancing market is an intricate institutional arrangement that makes sure that the balance between electricity supply and demand is maintained. In the light of the development of a single electricity market in Europe, harmonization and integration of currently national balancing markets have...

Power system operation with large-scale wind power in liberalised environments

Our society revolves around electricity. Most electricity is produced from fossil fuels, such as coal and natural gas. The disadvantages are that their supply is finite and unevenly distributed across the earth. Conventional power stations also emit greenhouse gases. Therefore, sustainable alternativees must be developed, such as wind power. The...
