Economic properties of an integrated wind power plant (WPP) and the demand response (DR) programs in the sample electricity market are studied. Time of use (TOU) and direct load control (DLC) are two of the DR programs that are applied in the system. The influences of these methods and the incentive payments by market operator's (MOs) with variable elasticity are studied. It is observed that DR with TOU and DLC programs together yields better revenue and energy saving for MOs.

In this paper, a new continuously and linearly controlled capacitive static VAR compensator is proposed for the automatic power factor correction of inductive single phase loads in 220V 50Hz power system networks. The compensator is constructed of a harmonic-suppressed TCR equipped with a new adaptive current controller. The harmonic-suppressed TCR is a new configuration that includes a thyristor controlled reactor (TCR) shunted by a passive third harmonic filter. In addition, the parallel configuration is connected to an AC source via a series first harmonic filter. The harmonic-suppressed TCR is designed so that negligible harmonic current components are injected into the AC source. The compensator is equipped with a new adaptive closed loop current controller, which responds linearly to reactive current demands. The no load operating losses of this compensator are negligible when compared to its capacitive reactive current rating. The proposed system is validated on PSpice which is very close in terms of performance to real hardware.

Membrane-based separation is a promising technology for hydrogen separation and purification due toits low energy consumption. Conventional membranes, such as polymeric membranes, often suffer frompermeability-selectivity trade-offs weakening their potential for challenging gas separations. Metalorganicframeworks (MOFs) with uniform apertures, high porosities, large internal surface areas, and tunablefunctionalities make them excellent fillers in mixed matrix membranes (MMMs) fabrication forhydrogen separation. This review evaluates current state-of-the-art MMMs performances, explores thechallenges in MMMs fabrication, and discusses current strategies in MOF-based MMMs fabrication andmodification aspects to enhance the membrane performance, specifically for H2/CO2, H2/CH4, and H2/N2 separation. Moreover, the hydrogen separation performance of MOF-based MMMs at elevated temperaturesand pressure and improvement in antiaging and antiplasticization properties are discussed indetail. The outlook and perspectives for MOF-based MMMs for hydrogen separation are also provided. This review offers insight into the potential of MOFs as porous fillers in MMMs fabrication for hydrogenseparation application.
