The ease of expansion of power system and lowered cost made the use of modular converters in Renewable Energy System more common. Different configurations are implemented depending on the applications. Control strategies like fuzzy logic, droop method and charge control scheme are developed for achieving sharing of current and voltages among the converters. In this paper new modularization architecture...
This paper proposes the finite control set applied to the current control of an interleaved boost converter of photovoltaic systems. The proposed controller select the state of the converter semiconductor by using the predicted behavior of the converter and the minimization of a cost function. Hence, the controller guarantees that the current reference is reached. The current reference is computed...
In this article a sliding mode plus PI controller is proposed to control of the voltage and the input current of a photovoltaic system. The proposed nonlinear controller is designed to control the duty cycle of the two level interleaved boost converter due to changes in the operating conditions of the photovoltaic panel (changes in irradiance levels). Besides this, the proposed controller can operate...
Using renewable sources to meet the load demand in the distribution level has become more economical and prevalent. The integration of these sources has impact on the load flow direction and magnitude. These changes can affect the operation of overcurrent (OC) relays as the main protective device in medium voltage (MV) distribution networks. In other words, the changes in the current magnitude and...
