Tidskriftsartikel (refereegranskat)abstract
- Electricity Systems in europe are experiencing major changes due to targets for renewable energy integration, reducing greenhouse gas emissions, and energy efficiency. Different studies show that there is a growing need for more flexibility and active stakeholder involvement at all levels (from small consumers to pan-European networks) to ensure the efficient and reliable operation of the electricity system, particularly to deal with growing volumes of renewable energy sources, from transmission-level wind and solar farms to household-level photovoltaic generation. Other key evolutions that aim to decarbonize the energy sector beyond electricity, such as those based on the electrification of energy end uses (e.g., the development of electric vehicles and the electrification of heating), are also expected to have a substantial impact.

- Energy production and consumption activities account for 76% of global greenhouse gas (GHG) emissions, according to the Historical GHG Emissions database by Climate Watch. Power and heat plants cause 42% of energy-related GHG emissions, while other sectors, like transport, other energy use in buildings, and industry, cause 22%, 8%, and 24% of energy-related GHG emissions, respectively.

Designing for High-Voltage dc Grid Protection : Fault Clearing Strategies and Protection Algorithms
- 2019
-
Ingår i: IEEE Power and Energy Magazine. - : IEEE Press. - 1540-7977 .- 1558-4216. ; 17:3, s. 73-81

Tidskriftsartikel (refereegranskat)abstract
- Protecting High-Voltage (HV) dc grids requires a different approach compared with that of ac power system protection and poses one of the major challenges that must be resolved before the realization of large scale HVdc grids that use equipment from multiple vendors. HVdc grid protection, which is essential for safe and reliable HVdc grid operation, entails the appropriate detection and fault clearing of dc-side short circuit faults (i.e., dc faults). In this context, fault clearing refers to interrupting the dc fault current and isolating the faulted component. Fault current interruption is much more complex in HVdc grids compared to ac systems because dc fault currents have no naturally recurring zero crossings and, without countermeasures, quickly increase to values that are unacceptable for power electronic components. Conversely, the technologies used within HVdc grids offer options for fault clearing beyond the well-known approach of using circuit breakers in existing ac systems.

The Race to Realize Small Modular Reactors : Rapid Deployment of Clean Dispatchable Energy Sources
- 2024
-

- Small modular reactors (SMRs) are currently touted as the next evolution of nuclear energy. They are a type of nuclear reactor designed to be smaller in size than a traditional reactor. Nevertheless, they are based on the same fission technology that splits atoms to create heat, which can then be used to generate electricity. SMRs can offer clean, reliable power and heat at manageable costs for both on- and off-grid communities. Currently, there are more than 100 proposed SMR reactor designs worldwide participating in the race to commercialization. This article presents a comprehensive review of the different SMR technologies that are currently being developed. The technical characteristics of the SMRs have been evaluated to provide insights into their complementary role in a renewable energy system and highlight how they can accelerate the journey toward a deeply decarbonized world.

Taking Credit : The Impact of Wind Power on Supply Adequacy-Experience from the Swedish Market
- 2010
-
Ingår i: IEEE POWER ENERGY MAG. - 1540-7977. ; 8:5, s. 47-52
-
Tidskriftsartikel (refereegranskat)abstract
- This article presents some general concepts about capacity credit values, which are illustrated by theoretical examples as well as practical experience from the Swedish electricity market. The capacity credit of a wind generating unit (or a block of generating units) represents the contribution of the unit to the supply adequacy of the system. The capacity credit of a power plant is an abstract quantity based on probability calculations and requires knowledge of the probability distributions for available generation capacity and load. To secure the reliability of supply, the Swedish system operator was given the responsibility to purchase annual contracts for a "power reserve".

The flexibility workout : Managing variable resources and assessing the need for power system modification
- 2013
-
Ingår i: IEEE Power & Energy Magazine. - 1540-7977. ; 11:6, s. 53-62
-
Tidskriftsartikel (refereegranskat)abstract
- Power systems have been designed and operated so that the demand for electricity can be met at all times and under a variety of conditions. Depending on the season, the climate, and the weather, demand can fluctuate significantly over a single day, week, or month. For example, in France the extensive use of electricity to generate heating creates a relationship between increase in electricity demand and decrease in temperature that amounts to close to 2,400 MW/°C. In addition to meeting the variability requirements, there is always some inherent uncertainty about future demand and the future availability of generators. The power system must thus be able to manage both variability and uncertainty.

Forskningsöversikt (refereegranskat)abstract
- Battery energy storage effectively staBIlizes the electric grid and AIDS renewable integration by balancing supply and demand in real time. The importance of such storage is especially crucial in densely populated urban areas, where traditional storage techniques such as pumped hydroelectric energy storage and compressed-air energy storage are often not feasible.
