The use of Direct Current (DC) transmission links in power systems is increasing continuously. Thus, it is important to develop new techniques to model the inclusion of these devices in network analysis, in order to allow studies of the operation and

This paper presents a new methodology for static VAr compensator (SVC) modeling in the power flow problem. The proposed formulation applies sigmoid functions to model the control equations that describe SVCs' steady-state behavior, including their li

An alternative power flow formulation, called linear power flow or “dc” power flow (DCPF), consists in the consideration of some simplifications regarding the network representation, leading to a linear problem formulation of low-cost computation

Bulk power systems failures caused by voltage instability phenomena have become more frequent during the last years. Voltage control schemes capable of keeping voltage magnitude within specified limits, automatically, for a specific area of the power

This study presents a new methodology to determine the optimal Offshore Wind Farms connection point in a power system, with the purpose of maximising the wind power penetration, considering a Benders decomposition approach to represent the security c

This paper describes a new methodology to identify conflicts between power flow control devices that can cause New-ton's method convergence problems. The proposed technique is based on applying the principal component analysis (PCA) to the control se

The technical, economic, and environmental constraints related to the construction of new transmission lines are complex issues related to the definition of points for connecting new offshore wind farms (OWFs) to the grid. In this context, it has bec

This study presents two approaches to handling under-frequency regulation in isolated microgrids. The first one is a governor power flow (PF) model in which the generators steady-state governor equations are modeled into a full Newton PF formulation
