Recently researchers have focused on the optimal operation of droop-controlled islanded microgrids (DCIMG). However, most papers consider only economic objective. But, with increasing focus environmental compliance, it has also become necessary to reduce emission from generation activities. Furthermore, previous do not heat demand in microgrid and uncertainties involved load renewable forecasting. This paper bridges all these gap areas by presenting a method for determining droop settings...

An AC–DC hybrid microgrid is gradually becoming popular. For economic viability and environmental sustainability, an should be operated optimally.

In this study, the authors present a linear power flow method for droop-controlled DC microgrids (MGs). Traditional techniques do not apply to DCMGs owing and voltage flexibility capability of dispatchable generation units. Therefore, new embodying droop-control operation philosophy were developed by researchers. The existing methods are time-consuming since they involve iterative solutions set non-linear equations. proposed is accurate, simple, gives faster results in comparison methods....

This paper proposes a method to determine the droop settings of dispatchable distributed generation units for optimal operation droop-controlled DC microgrid. Presently, it is necessary not only generate power economically but also with minimum emission. Therefore, objectives considered in this are 1) minimizing total operating cost (TOC); 2) emissions from activities. The bi-objective optimization process solved using fuzzy max-min principle. Particle swarm used find optimum values....

In this paper, a power flow method and an economic dispatch model of microgrid with feeder control (FFC) distributed generators (DGs) are formulated. When FFC DGs present, the exchanges prescheduled amount active reactive main grid, therefore, substation is known priori. Under such circumstance, conventional classification system buses into slack, load generator not sufficient, bus has to be extended. So, new technique capable dealing situation formulated in paper.

A battery energy storage system (BESS) plays a crucial role in the proper operation of microgrid. Larger size BESS, smaller is microgrid operating cost, but higher BESS's capital cost. Thus, compromise between cost and investment to be reached for determining optimal BESS size.

A modern energy system should be reliable, economically viable, and environment-friendly. This paper addresses the above issue by proposing a probabilistic approach of optimally placing sizing distributed generation shunt capacitors in distribution network.
