Weight and power optimization of steam bottoming cycle for offshore oil and gas installations

Nord, Lars O.; Martelli, Emanuele; Bolland, Olav - In: Energy 76 (2014) C, pp. 891-898

, single-objective optimization was first used to determine the solution with minimum weight-to-power ratio, then multi-objective … turbine and condenser to achieve a higher steam cycle power output than the reference cycle. For the multi-objective … optimization was applied to identify the Pareto frontier of solutions with maximum power and minimum weight. The optimized solution …

Optimum sizing of wind-pumped-storage hybrid power stations in island systems

Papaefthymiou, Stefanos V.; Papathanassiou, Stavros A. - In: Renewable Energy 64 (2014) C, pp. 187-196

Pumped storage is generally viewed as the most promising technology to increase renewable energy source (RES) penetration levels in power systems and particularly in small autonomous island grids. Combined wind and pumped-storage “virtual power plants”, called hybrid power stations (HPS),...

Multi-Objective Quantity–Quality Reservoir Operation in Sudden Pollution

Shokri, Ashkan; Haddad, Omid Bozorg; Mariño, Miguel - In: Water Resources Management 28 (2014) 2, pp. 567-586

Damage caused by entered pollution in reservoirs can affect a water resource system in two ways: (1) Damages that are caused due to consumption of polluted water and (2) damages that are caused due to insufficient water allocation. Those damages conflict with each other. Thus, the crisis should...
