  • This paper presents a new method for solving a long term unit commitment problem including hydro and pumped storage hydro units in a large scale power system. The proposed method makes it possible to get variable power of hydro and pumpde storage hydro units and results in the better unit commitment with good convergency. Moreover this paper proposes an unit commitment algorithm to consider variable power of these units effectively by Lagrangian Relaxation method. By applying the proposed method to the test system and the real system, it is verified the usefulness of this method.

  • In order to vitrify the W1 waste (ion-exchange resin(IER), zeolite, and dry active waste(DAW)) generated from Korean Nuclear Power Plants, a glass formulation development based on waste compositions and production rates was performed. A aluminoborosilicate glass, AG8W1, was formulated to vitrify the W1 waste in an induction cold crucible melter(CCM). The processability, product performance, and economics of the candidate glass were calculated using a computer code and were measured experimentally in the laboratory and CCM. The glass viscosity and electrical conductivity as the process parameters were in the desired ranges. Start-up and maintaining glass melt of the candidate glass were favorable in the CCM. The product quality of the glass such as chemical durability, phase stability, etc. was satisfactory. The vitrification process using the candidate glass was also evaluated to be operated as economically as possible.

  • Small Hydro-Power (SHP) is an environmental friendly technology. Usually hydro power generation projects are viewed as constructing large dams and reservoirs but available new research and engineering techniques have helped hydro power generation without large dams and without large reservoirs. In India, there are several water installations, irrigation dams, canals, streams or running rivers not tapped to generate power. In these cases the existing system and facilities can help in generating power with less investment and time. This area is yet unexplored. Harnessing a stream for hydroelectric power is a major undertaking for the energy crises and the global issues to go green. In this technical note a potential site for mini hydro power plant nearby Shoolini University is identified and examined for the economic feasibility.
