The focus of this paper is on studying power control for Interlinking Converters (ICs) to maintain stable voltage frequency on both AC and DC sides for a hybrid AC/DC microgrid in standalone mode, as well as the balance of active and reactive power. The control method also enhancing the resilience of the hybrid AC/DC microgrid during sudden load increases or power source failures in the AC and DC subgrids.

This paper studies on establishing the mathematical optimization formulation to coordinate the operating times of directional overcurrent relays in transmission networks. The objective function of this optimization formulation is to minimize the total operation time of all directional overcurrent relays, and it must satisfy the highly nonlinear constraints such as the time multiplier setting range, the plug setting range, and the coordination time interval between the primary and backup relay pair.

This research presents a detailed evaluation of the total active power loss (TAPL) under different placements of photovoltaic power plants (PVPs) in the electric distribution network (EDN) IEEE 33-node. Three study cases have been conducted to serve the initial intention, including 1) optimizing both rated power and position of a PVP on selected EDN; 2) optimizing the positions of different quantities of PVPs independently to the grid with the same rated power, and 3) optimizing a sole PVP with a wide range of rated power.

This paper presented the application of Direct Contact Membrane Distillation (DCMD) for the treatment of the secondary effluent of a municipal wastewater treatment plant (WWTP) to produce fresh water. The purification studies conducted at various feed temperatures demonstrated that the permeate water flux increased and that the water flux decreased quickly at the higher feed temperature.
