Microgrid concept is one of the suitable strategies for increasing resilience and preventing load curtailment, especially in emergency conditions. Operation islanded mode unique features microgrids that can provide numerous benefits both consumers energy producers. Unlike conventional distribution networks, reconfigurable enable reconfiguration process to achieve optimal structure. In this article, a new strategy scheduling considering islanding capability constraints presented. To...

By increasing environmental pollution and the energy crisis, development of renewable sources (RESs) has become an essential option to ensure a sustainable supply. However, inherent uncertainty RESs poses significant technical challenges for independent system operators (ISOs). Transmission line congestion one ISOs use maximum power RESs. The mobile battery-based storage systems can provide promising solution transportation generated from load centers mitigate effects on network operation....

Coordinated multi-carrier energy systems with natural gas and electricity energies provide specific opportunities to improve efficiency flexibility of the supply. The interdependency networks faces multiple challenges from power flow in corresponding feeders pipes connection points between two infrastructures’ view. However, hub concepts as fundamental concept conversion, storage, generation facilities can be considered a point grids. Hence, this paper proposes an optimal operation...

Abstract The structure–property relationships of polypropylene/ethylene-propylene-diene (PP/EPDM) (80/20) nanocomposites containing single-walled carbon nanotubes (SWCNTs) by melt-mixing process were investigated, the main focus being on effect SWCNTs concentration and compatilizer content. Morphological observations scanning electron microscopy (SEM) are presented in conjunction with mechanical, thermal, rheological properties these nanocomposites. tensile modulus was enhanced increasing...

Likewise, price-sensitive shiftable (PSS) demand bidding approach applied increase flexibility power grid operation and reduce carbon emissions system. main objective proposed determine optimal...

Abstract The morphology of some ternary blends was investigated. In all the polypropylene, as major phase, blended with two different minor phases, ethylene–propylene–diene terpolymer (EPDM) or ethylene–propylene–rubber (EPR) first phase and high‐density polyethylene (HDPE) polystyrene (PS) second phase. All were investigated in a constant composition 70/15/15 wt %. Theoretical models predict that dispersed multiphase polymer blend will either form an encapsulation‐type phases remain...

One of the primary concerns in banking industry is to measure relative importance using popular multi criteria decision making (MCDM) techniques such as data envelopment analysis (DEA) and Technique for Order Preference by Similarity Ideal Solution (TOPSIS).In this paper, we use these two MCDM efficiencies 16 private governmental banks terms electronic payment.There are three inputs with DEA methods including number issued cards, ATM machines POSs there outputs successful ATMs...

Abstract Simple blends with different viscosity ratios of the components as well compatibilized varying both in type and content compatibilizers were used to study relation between interfacial tension dispersed‐phase particle size for PP/EPDM (80/20 wt %) this work. Four compatibilizing systems, poly(ethylene‐ co ‐methacrylic acid) ionomers (EMA–I), dicumyl peroxide (DCP), DCP combined EMA–I, combination trimethylol propane triacrylate (TMPTMA), used. For prepared an internal mixer, a power...

The rheology and morphology of multi-walled carbon nanotube (MWNT)/polypropylene (PP) nanocomposites prepared via melt blending was investigated. minor phase content MWNT varied between 0.25 8 wt%. From morphological studies using a scanning electron microscopy technique good dispersion nanotubes in the PP matrix observed. rheological were performed by capillary rheometer, mechanical properties studied tensile flexural tester. Both its showed non-Newtonian behavior. At low shear rates...

Future smart distribution networks will include micro-grids (MGs) that are working in the neighbourhood. Owing to penetration of renewable energy sources with probabilistic nature as well deviation load, MG may be faced an overload or surplus power. The solution this problem is create and control a link between neighbour MGs for power exchange management. This study proposed new framework optimal scheduling reconfigurable neighbouring (NMGs). Reconfiguration by managing connection MGs,...

Abstract This paper elaborates on optimal scheduling of coordinated power and natural gas (NG) networks in the presence interconnected energy hubs considering reconfiguration as a flexibility source. With regard to hub system consisting several generation units, storage conversion technologies, well gas‐fired high interdependency between electricity carriers should be captured. The hourly capability is developed for first time multi‐energy enhance dispatch consumption pattern. realistic...

Globally, the dual challenges of power shortages and waste management underscore critical need for innovative sustainable energy solutions. Addressing these issues is essential achieving environmental sustainability, economic development, social well-being. This paper proposes an integrated life cycle sustainability assessment (LCSA) waste-to-electricity (WtE) technologies future mix in Western Lombok, Indonesia which strongly faces shortage challenges. The proposed LCSA assesses three WtE...

Abstract A series of polypropylene (PP) nanocomposites containing 2, 4, and 6 wt % an organophilic montmorillonite clay was prepared via direct melt mixing in the presence maleic anhydride grafted (PP‐ g ‐MAH) as compatibilizing agent. Microstructure characterization performed by X‐ray diffraction analysis. Nanocomposites exhibited a 15 22% enhancement tensile modulus impact strength, respectively.

Abstract Morphology and linear viscoelastic properties of PA/PE/Clay blend nanocomposites with without compatibilizer (PE‐ g ‐MA) PA as a matrix phase were studied. Using rheological XRD analyses, it was shown that the clay exhibited higher dispersion in PA/PE than pure PA. It attributed to detachment intercalated layers due stress transfer PE particles deformation flow field created between particles, leading formation stronger network. The presence PE‐ ‐MA further enhanced blend. While...
