The loss of balanced voltages involves a voltage drop due to symmetric three-phase errors, or the initiation of high-power three-phase loads or symmetric three-phase switches. While these events in an unbalanced way lead to asymmetric voltage drops. Voltage drops can cause asymmetric load on the power grid, the occurrence of volatility, and even network power outage. One of the most common ways...
In this paper, several optimum structures of a cascaded multilevel inverter is proposed. This optimization is based on generation a constant number of output voltage levels by using minimum number of power switches or dc voltage sources or minimum amount of blocked voltage by power switches. In addition, the optimum structure for a constant number of dc voltage sources by using minimum number o...
Bargaining Power is one of the important issues in oil trade negotiations. In this paper two effective factors in bargaining power i.e. patient time to deal and outside options of each player have been considered. The necessary relations for exchange of sources in negotiation have been derived.
In this study, balanced and single ended class-E power amplifiers (PAs) were designed and realized for 3.5–3.8GHz band by using Gallium Nitride high electron mobility transistor (GaN HEMT). Realizations were made on low loss Rogers RT5880 dielectric material which has 0.254mm thickness and 2.2 dielectric constant. Proposed balanced class-E PA has approximately 20W (43 dBm) output power with 80%...
This paper presents an effective solution to overcome the problem caused by intermittent energy sources that are connected a balanced/unbalanced distribution system using superconducting magnetic storage (SMES) mitigating voltage and frequency fluctuations during wind gusts. The fuzzy logic control technique (FLC) is used with SMES improve frequency. A squirrel cage induction generator (SCIG) a...
Increasing power demands require multiple generating units interconnected with each other to maintain the balance of system. This results in a highly dense system consisting which coordinate balanced performance Among different energy sources, thermal source, hydro photovoltaic system, and wind source are most popular ones. Researchers have developed several optimization problems literature kno...
In this paper, a novel control strategy for a Shunt Active Power Filter (shunt-APF) is proposed. In the proposed control strategy which is based on a new application of the instantaneous reactive power theory, the current injected by the shunt-APF is capable of compensation for the reactive component, the harmonic components and also unbalance of the load current. In this strategy, the shunt-AP...
