Paper presents a three-phase current-based model of FACTS devices for power flow calculation with Newton-Raphson method. First, it presents the basic method of three-phase current-based modelling of FACTS devices, together with existing three-phase model of FACTS devices and the type of FACTS devices. Next, determinations of controlled parameters depending on the type and usage of FACTS devices are presented. At the end numerical examples in the IEEE 300 bus system are presented. The problem of initial values is exposed and superiority of the new method by comparison with the existing ones

The paper addresses a stochastic generation-expansion planning model in the interdependent operation of an electric power system (EPS) and a natural gas system (NGS). The objective of the proposed optimization model is to provide consumers with a reliable electric energy supply by proper generation-expansion planning and diversification of energy transmission paths with minimal investment and operating costs. The proposed method takes into account constraints in the EPS and NGS. The Monte Carlo simulation method is applied to consider random outages of EPS and NGS elements and inaccuracies in the long-term electric load forecasting.

Low-voltage (LV) grid feeders with high penetration of photovoltaics (PVs) are often affected by voltage magnitude problems. The use of electric vehicle (EV) public charging stations with energy storage system (ESS) was introduced as a solution for voltage regulation in LV feeders with PV. A novel method was proposed to determine the ESS charging load required for voltage regulation and compare the results for the different locations in the feeder.
