- A Centralized Smart Decision-Making Hierarchical Interactive Architecture for Multiple Home Microgrids in Retail Electricity Market
A1 Alkuperäisartikkeli tieteellisessä aikakauslehdessä(2018) Javadi, Masoumeh; Marzband, Mousa; Akorede, Mudathir Funsho; Godina, Radu; Saad Al-Sumaiti, Ameena; Pouresmaeil, EdrisThe principal aim of this study is to devise a combined market operator and a distribution network operator structure for multiple home-microgrids (MH-MGs) connected to an upstream grid. Here, there are three distinct types of players with opposite intentions that can participate as a consumer and/or prosumer (as a buyer or seller) in the market. All players that are price makers can compete with each other to obtain much more possible profitability while consumers aim to minimize the market-clearing price. For modeling the interactions among partakers and implementing this comprehensive structure, a multi-objective function problem is solved by using a static, non-cooperative game theory. The propounded structure is a hierarchical bi-level controller, and its accomplishment in the optimal control of MH-MGs with distributed energy resources has been evaluated. The outcome of this algorithm provides the best and most suitable power allocation among different players in the market while satisfying each player’sgoals. Furthermore, the amount of profit gained by each player is ascertained. Simulation results demonstrate 169% increase in the total payoff compared to the imperialist competition algorithm. This percentage proves the effectiveness, extensibility and flexibility of the presented approach in encouraging participants to join the market and boost their profits. - Discovery of Periodinane Oxy-Assisted (POA) Oxidation Mechanism in the IBX-Controlled Oxidative Dearomatization of Pyrroles Mediated by Acetic Acid
A1 Alkuperäisartikkeli tieteellisessä aikakauslehdessä(2022-10-07) Farshadfar, Kaveh; Gunawan, Nina; Shiri, Farshad; Howard, James K.; Vaas, Andaravaas Patabadige Jude P.; Bissember, Alex C.; Yates, Brian F.; Smith, Jason A.; Ariafard, AlirezaThe 2-iodoxybenzoic acid (IBX)-controlled oxidative dearomatization of pyrroles occurs very slowly (or not all) in many organic solvents, including DMSO in which IBX is soluble. Interestingly, although IBX is only partially soluble in acetic acid, this solvent mediates the pyrrole oxidative dearomatization. With the aid of density functional theory (DFT) calculations, we have discovered a new mode of reactivity, termed the periodinane oxy-assisted (POA) oxidation mechanism, which explains this observation. - The Impact of Demand Response Programs on Reducing the Emissions and Cost of A Neighborhood Home Microgrid
A1 Alkuperäisartikkeli tieteellisessä aikakauslehdessä(2019) Fouladfar, Mohammad Hossein; Loni, Abdolah; Bagheri Tookanlou, Mahsa; Marzband, Mousa; Godina, Radu; Saad Al-Sumaiti, Ameena; Pouresmaeil, EdrisThe desire to increase energy efficiency and reliability of power grids, along with the need for reducing carbon emissions has led to increasing the utilization of Home Micro-grids (H-MGs). In this context, the issue of economic emission dispatch is worthy of consideration, with a view to controlling generation costs and reducing environmental pollution. This paper presents a multi-objective energy management system, with a structure based on demand response (DR) and dynamic pricing (DP). The proposed energy management system (EMS), in addition to decreasing the market clearing price (MCP) and increasing producer profits, has focused on reducing the level of generation units emissions, as well as enhancing utilization of renewable energy units through the DR programs. As a consequence of the nonlinear and discrete nature of the H-MGs, metaheuristic algorithms are applied to find the best possible solution. Moreover, due to the presence of generation units, the Taguchi orthogonal array testing (TOAT) method has been utilized to investigate the uncertainty regarding generation units. In the problem being considered, each H-MG interacts with each other and can negotiate based on their own strategies (reduction of cost or pollution). The obtained results indicate the efficiency of the proposed algorithm, a decrease in emissions and an increase in the profit achieved by each H-MG, by 37% and 10%, respectively.
