Modern distribution systems and microgrids must deal with high levels of uncertainty in their planning operation. These uncertainties are mainly due to variations loads distributed generation (DG) introduced by new technologies. This scenario brings challenges planners system operators that need tools perform more assertive analyses the grid state. paper presents an optimization methodology cap...

The problem of power allocation is studied for a multiple-input multiple-output (MIMO) decode-and-forward (DF) two-way relaying system consisting of two source nodes and one relay. It is shown that achieving maximum sum-rate in such a system does not necessarily demand the consumption of all available power at the relay. Instead, the maximum sum-rate can be achieved through efficient power allo...

In this paper, a transmitting power allocation strategy for users jointed together pre-coding is presented to eliminate interusers interference and improve the energy efficiency of Massive MIMO systems. The power allocation model is formularized as energy efficiency optimization problem of the users ’ power and circuit power consumption. We demonstrate that energy efficiency is a convex functio...

In this paper, an optimal strategy is proposed for the reactive power allocation in large-scale grid-connected photovoltaic systems. Grid-connected photovoltaic systems with direct current to alternating current inverters are able to supply active power to the utility grid as well as reactive power. The active power, extracted by the direct current to alternating current inverters, is usually c...
