"Dispatch Strategy Based Optimized Design of an Offgrid Hybrid Microgri" by Md Fatin Ishraque, Md Mortuza Ali et al.

An optimal design and evaluation of a hybrid microgrid consisting of different renewable sources according to five dispatch methods is conducted in this research. The optimal design, costing and environmental impact of the proposed micro-grid have been performed in HOMER Pro software environment. Feasibility and power system response analysis of the proposed microgrid have been performed in MATLAB/Simulink software environment. Consequently, the best and worst dispatch methods for the proposed microgrid have been identified based on the performance of different dispatch techniques. Also, a comparative study is presented in this paper, among the designed microgrid, other hybrid microgrid and other conventional power stations. The results show that the proposed microgrid has reduced cost and emission of harmful gas than the other designs and it also offers feasible and stable power system responses. The study includes five dispatch strategies and among them, load following is found as th ....

"Consensus-based decision making approach for techno-economic operation" by Arian Zahedmanesh, Kashem M. Muttaqi et al.

Utility-scale battery energy storage systems (BESSs) are emerging as an essential part of future power grids. A framework for the techno-economic application of a BESS in a dc coupled hybrid microgrid serving a mining industry is presented. Specifically, a multi-level consensus-based decision-making (MCD) approach is proposed for the energy management of the microgrid and the active/reactive power control of the microgrid's converters. The MCD can promote the operation of microgrids in the national electricity market as an economic unit. Also, the heterogeneous power curve of mining machines, the intermittency of renewables and the uncertainties of power systems can be addressed with reduced complexity. Whilst, the utility grid can apply and lead the regulatory parameters for the power system, as well as the microgrid, in accordance with the generator performance standards (GPS). A detailed electromagnetic transients (EMT) model is developed in PSCAD for a realistic test system an ....

"Optimization of a grid-connected microgrid using tidal and wind energy" by Navid Majdi Nasab, Md Rabiul Islam et al.

The Cook Strait in New Zealand is an ideal location for wind and tidal renewable sources of energy due to its strong winds and tidal currents. The integration of both technologies can help to avoid the detrimental effects of fossil fuels and to reduce the cost of electricity. Although tidal renewable sources have not been used for electricity generation in New Zealand, a recent investigation, using the MetOcean model, has identified Terawhiti in Cook Strait as a superior location for generating tidal power. This paper investigates three different configurations of wind, tidal, and wind plus tidal sources to evaluate tidal potential. Several simulations have been conducted to design a DC-linked microgrid for electricity generation in Cook Strait using HOMER Pro, RETScreen, and WRPLOT software. The results show that Terawhiti, in Cook Strait, is suitable for an offshore wind farm to supply electricity to the grid, considering the higher renewable fraction and the lower net present cost i ....

"A new voltage regulation strategy using developed power sharing techni" by Bilal M. Eid, Josep M. Guerrero et al.

Integration of solar photovoltaic (PV) sources to power grid is increasing rapidly in recent years. Since the PV source is an intermittent source, this causes many challenges to distribution network. To overcome these challenges, a voltage regulation strategy using a developed power management technique for microgrid system is proposed. The technique is based on voltage ride through capability. The active and reactive power flow along with the voltage profile has been deeply investigated to improve the stability of the distribution network. As a testing environment, three microgrid configurations developed in MATLAB/Simulink have been investigated. The study shows a faster response time and lower circulating current in configuration 2. Moreover, it revealed the effectiveness of the power management technique when a cluster of dispatchable and non-dispatchable distributed generators is in operation. ....
