In the title compound, C 21H 25N 3O 6S, the dihedral angle between the meth-oxy-benzene and indazole rings is 74.96 (5)°. The crystal packing is stabilized by an N-H⋯O hydrogen bond into a two-dimensional network. In addition, C-H⋯π inter-actions and a π-π contact, with a centroid-centroid distance of 3.5333 (6) Å, are observed. The crystal packing is stabilized by N-H⋯O and C-H⋯O hydrogen bonds.

The molecule of the title heterocyclic compound, C16H 17N3O3S, is bent at the S atom with an C-SO2-NH-C torsion angle of 80.17 (8)°. The phenyl substituent at the S atom is rotated out of the plane of the 1H-indazole ring [inter-planar angle = 46.24 (8)°]. In the crystal, intermolecular N-H⋯N and N-H⋯O hydrogen bonds build up a ribbon developing parallel to the b-axis direction. C-H⋯O hydrogen bonds link these ribbons, forming a layer parallel to the bc plane.

In the title compound, C 19H 21N 3O 3S, the C - SO 2 - NH - C torsion angle is 103.72 (11)°. The almost planar indazole ring [r.m.s. deviation = 0.0202 (14) Å] is twisted away from the methyl-benzene ring by 76.87 (7)°. The vinyl group is disordered over two orientations with site occupancies of 0.622 (10) and 0.378 (10). The S atom has a distorted tetra-hedral geometry [maximum deviation: O - S - O = 119.18 (11)°]. An intra-molecular C - H⋯O hydrogen bond occurs. In the crystal, two mol-ecules are linked about a center of inversion by pairs of N - H⋯O hydrogen bonds, generating a dimer. C - H⋯π inter-actions are also observed. © Abbassi et al. 2011.

In the title mol-ecule, C 11H 12N 2O, the pyridazine ring has a skew-boat conformation. The dihedral angle between the phenyl ring [r.m.s deviation = 0.0039 (15) Å] and the best mean-plane of the pyridazine ring [r.m.s deviations = 0.2629 (15) Å] is 53.27 (10)°. In the crystal, mol-ecules are linked by C - H⋯O hydrogen bonds and C - H⋯π inter-actions involving the methyl group and the phenyl ring of a symmetry-related mol-ecule. © Sekkak et al. 2011.

In the title compound, C19H21N3O 3S, the C - SO2 - NH - C torsion angle is 66.20 (9)°. The dihedral angle between the benzene ing and the essentially planar indazole ring system [r.m.s. deviation = 0.0361 (1) Å] is 72.97 (6)°. The S atom has a distorted tetra-hedral geometry [maximum deviation = O - S - O = 119.30 (6)°]. The crystal structure features inversion-related dimers linked by pairs of N - H⋯O hydrogen bonds. In addition, weak C - H⋯O interactions may stabilize the crystal packing.

This paper presents a model predictive control (MPC) approach for the optimization of the energy produced by a microgrids (MGs) in a network. The objective is to present a control approach for interconnected cooperating MGs, where the main objective is to minimize the power purchased by each MG. Minimizing the energy purchased from other MGs and from the main grid is considered among main objectives to be achieved. In order to reach these objectives, a global central controller is responsible to find the best patterns for state of energy storage system and the power exchanges among MGs, where each MG can be modeled as an inventory system, locally producing energy by wind turbines. The MPC strategy is tested using an interconnected network of three MGs. Results provide a good reference on the economic benefits which can be obtained using MPC. © 2014 IEEE.
