2. 1. Distributed Stochastic Programming with Applications to Large-Scale Hydropower Operations

   Author : Martin Biel; Mikael Johansson; Lennart Söder; David Woodruff; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; stochastic programming; distributed; algorithms; large-scale; optimization; hydropower; software; julia language; Electrical Engineering; Elektro- och systemteknik;

   Abstract : Stochastic programming is a subfield of mathematical programming concerned with optimization problems subjected to uncertainty. Many engineering problems with random elements can be accurately modeled as a stochastic program. In particular, decision problems associated with hydropower operations motivate the application of stochastic programming. READ MORE

4. 2. Essays on Energy and Climate Policy – Green Certificates, Emissions Trading and Electricity Prices

   Author : Anna Widerberg; Göteborgs universitet; []
   Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Attitudes; Carbon Dioxide; Carbon Intensity; Climate Change; Electricity; Electricity Prices; Emissions Trading; Emission Allowances; Environment; Fairness; GARCH models; Lyapunov Exponents; Market Structure; Personal Carbon Allowances; Public Opinion; Reconstructed Dynamics; Stability; Tradable Energy Quotas; Tradable Green Certificates; Volatility;

   Abstract : Paper I: An Electricity Trading System with Tradable Green Certificates and CO₂-emission Allowances Combinations of various policy instruments to deal with the threat of climate change are used throughout the world. The aim of this article is to investigate an electricity market with two different policy instruments, Tradable Green Certificates (TGCs) and CO₂ emission allowances (an Emission Trading System, ETS).

5. 3. Solar Variability Assessment in the Built Environment : Model Development and Application to Grid Integration

   Author : David Lingfors; Joakim Widén; Jan Kleissl; Uppsala universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar Variability; Photovoltaics; Grid Integration; Distributed Generation; LiDAR; GIS; Engineering Science; Teknisk fysik;

   Abstract : During the 21st century there has been a rapid increase in grid-connected photovoltaic (PV) capacity globally, due to falling system component prices and introduction of various economic incentives. To a large extent, PV systems are installed on buildings, which means they are widely distributed and located close to the power consumer, in contrast to conventional power plants. READ MORE

6. 4. On stochastic optimization for short-term hydropower planning

   Author : Yelena Vardanyan; Lennart Söder; Mikael Amelin; Afzal Siddiqui; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : Renewable generation is the fastest growing energy resources in the past decade. Renewable energy sources, particularly wind power, provide clean and environmentally friendly energy to meet the system demand, meanwhile introducing huge levels of uncertainty in the system. READ MORE

7. 5. Managing the introduction of reliability-centred maintenance, RCM : RCM as a method of working within hydropower organisations

   Author : Fredrik Backlund; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Kvalitetsteknik; Quality Technology and Management;

   Abstract : Due to a competitive environment, many companies are required to reduce their overall costs while maintaining the value and reliability of their assets. The use of Reliability-Centred Maintenance, RCM, can support organisations to develop an effective and efficient maintenance programme, meeting these requirements in a cost-effective manner. READ MORE
