Across the EU, significant infrastructure investment is needed in both generation from renewable energy sources (RES) and the electricity transmission system to meet the European targets on emission reduction and RES expansion. Experiences show, however, that citizens may object to new energy...

Many countries plan to decarbonise their energy systems by increasing energy efficiency and expanding the use of renewable energy sources (RES). Such actions require significant investments in new energy infrastructures. While people are generally accepting of these infrastructures, opposition...

Power systems based on renewable energy sources (RES) are characterised by increasingly distributed, volatile and uncertain supply leading to growing requirements for flexibility. In this paper, we explore the role of demand response (DR) as a source of flexibility that is considered to become...

Energy systems based on renewables have an increasing demand for flexibility. In this paper, we consider the potential of power-to-gas to provide flexibility and enhance the system integration of renewables. Existing research on power-to-gas typically analyses the system effects of a...

Managing the risk associated with uncertain load has always been a challenge for retailers in electricity markets. Yet the load variability has been largely predictable in the past, especially when aggregating a large number of consumers. In contrast, the increasing penetration of unpredictable,...

In this work, we study the profitability of energy storage operated in the Nordic, German, and UK electricity day-ahead markets during 2006-2016. We build a linear optimization model which maximizes profits from arbitraging hourly prices and use the model output of profits and storage cycles in...

Increased renewable generation worldwide is posing new challenges for power system planners. The location, as well as the level and operation, of each generation resource is increasingly important. This work presents a constrained Generation Expansion Planning (GEP) optimization model. One of...

As a result of government policies increasing the amount of electricity generated from fluctuating renewable sources in many countries, the requirement for flexibility in the corresponding electricity systems increases. On the demand side, load shedding is one demand response mechanism...

The growth in variable renewable energy (vRES) and the need for flexibility in power systems go hand in hand. We study how vRES and other factors, namely the price of substitute fuels, power price volatility, structural breaks, and seasonality impact the hedgeable power spreads (profit margins)...

Growth in energy demand together with the expansion of variable renewables has significant implications for the future electricity system. The increased volatility from growing intermittent production requires new sources of flexibility at a much greater scale to help maintain system balance. In...
