Power flow computations are important for operation and planning of the electricity grid, but computationally expensive because nonlinearities size system equations. Linearized methods reduce computational time often have disadvantage that they not applicable to general grids. In this paper we propose a novel linearized power (LPF) technique is able handle PQ- PV-buses, works on both transmissi...

A transformer-less unified power flow controller (UPFC) is a electronic device consisting of series and shunt voltage source converters (VSCs) that are not connected to common DC bus. It can control in medium (MV) distribution networks without the need for interfacing transformers. Hence there significant reduction size cost compared conventional UPFC. This paper investigates operating range UP...

Abstract Distributed power supply access to the system affects tidal distribution of network. The article establishes a mathematical optimization model with network loss minimization and load balance as objective function. In this paper, idea elite strategy is introduced into gravitational search algorithm combined Sigmoid function, an method reconfiguration based on improved proposed by improv...

Integrated energy systems (IESs) have attracted wide attention as effective frameworks to develop efficient use of resources. Proactive preparedness is a sensible approach for integrated distribution networks (IDNs) propitiously cope with high-impact rare (HR) events. In this paper, resilient-constrained two-stage expansion planning methodology proposed the aim simultaneously optimal IDNs and r...
