In this paper, we tackle the hydro unit commitment problem and scheduling in a valley. We first decompose into several simpler subproblems, one for each reservoir/plant. Then, model of them as an optimization on graphs with or without resource constraints. compare our method commercial solver mixed integer linear programming, run formulation show promising results.

This paper presents a decision making approach for mid-term scheduling of large industrial consumers based on the recently introduced class of Stochastic Dominance (SD)- constrained stochastic programming. In this study, the electricity price in the pool as well as the rate of availability (unavailability) of the generating unit (forced outage rate) is considered as uncertain parameters. Th...

The crystal structure of the title compound, (C(24)H(20)P)(2)[WS(4)], which was prepared under hydro-thermal conditions, contains tetra-phenyl-phospho-nium cations linked by supra-molecular inter-actions into chains running along the [110] and [10] directions. The [WS(4)](2-)anions, which lie on twofold axes, are located in the cavities created between the cation chains.

Most real-world optimization problems involve objectives, constraints, and parameters which constantly change with time. Treating such problems as a stationary optimization problem demand the knowledge of the pattern of change a priori and even then the procedure can be computationally expensive. Although dynamic consideration using evolutionary algorithms has been made for single-objective opt...

The paper addresses the unit commitment problem in power plant operation planning. For a real power system comprising coal and gas red thermal as well as pumped storage hydro plants a large-scale mixed integer optimization model for unit commitment is developed. Then primal and dual approaches to solving the optimization problem are presented and results of test runs are reported.

The title compound, Pr(SO(4))(OH), obtained under hydro-thermal conditions, consists of Pr(III) ions coordinated by nine O atoms from six sulfate groups and three hydroxide anions. The bridging mode of the O atoms results in the formation of a three-dimensional framework, stabilized by two O-H⋯O hydrogen-bonding inter-actions.

The title compound, [Cd(C(4)H(4)O(4))(H(2)O)(2)](n), has been synthesized under hydro-thermal conditions. The asymmetric unit consists of one Cd(2+) cation, one succinate anion and two aqua ligands. The Cd atoms present a distorted penta-gonal bipyramidal coordination and are bridged into layers parallel to (201) by succinate ligands.
