In power electronics systems the management of power loss and temperature of switching devices is indispensable for the reliability of the whole system. In this paper, a simple electro-thermal simulation model is presented. This simulation model is capable of predicting the power loss and estimating the junction temperature of power device in various environmental conditions. The electro-therma...

In regions with high penetration of Distributed Energy Resources (DER), grid congestion is mostly caused by power feed-in generators. this context, conventional approaches for solving the problems are Active Power Curtailment (APC) DER and reinforcement. wake increased generation, it not only interest how to obtain reinforcement, but also consider APC during planning. The challenge such plannin...

This paper presents a novel control approach used in shunt active power filter based on variable structure control combined with Random PWM technique (RVSC) that provides robust, fast, and more favorable performance for active power filter. This control strategy is compared with two other strategies to show the effectiveness of the introduced methods; pulse width modulated proportional-integral...

reactive power management plays an essential role in the secure operation of the power system as an ancillary service. although in electricity markets, the particular attention is paid to active power, the reactive power also plays an important on total generation costs of electricity. on the other hand, as it is mainly confined to local consumption, to avoid market power and maintain the secur...

Abstract: In modern wind farms, maximum power point tracking (MPPT) is widely implemented. Using the MPPT method, each individual wind turbine is controlled by its pitch angle and tip speed ratio to generate the maximum active power. In a wind farm, the upstream wind turbine may cause power loss to its downstream wind turbines due to the wake effect. According to the wake model, downstream powe...

There is an increasing interest in renewable and green energy sources and the integration of Distributed Generation DG into the power grid system. The problem of optimal capacitor allocation in electric distribution systems involves maximizing energy utilization, feeder loss reduction, and power factor correction. The feeder loss can be separated into two parts based on the active and reactive ...

When low output voltage and EN61000-3-2 compliance are put together, not too many options can be used, especially if the power range is between 300–600 W. This paper presents one of the best solutions to comply with both specifications at the same time: the use of a single-stage topology to comply with the low-frequency harmonic limits combined with a half-bridge converter with complementary co...

The wind energy industry is experiencing a strong growth in most countries in the last years. Several technical, economic and environmental benefits can be attained by connecting wind energy to distribution systems such as power loss reduction, the use of clean energy, postponement of system upgrades and increasing reliability. The doubly fed induction gen‐ erator (DFIG) is currently the most c...
