This paper analyzes the legislation in Latin America in relation with distributed generation. The policies of different countries in Latin America encourage the use of energy generation based on clean technologies, which are less dependent on coal derivatives. This has led to a growth in the use of renewable energy such as solar and wind power. Based on the results of this study the case of Colombia,...
The aim of this paper is to implement a microinverter to work in island mode and grid mode through a reconfigurable control scheme, depending on the operation mode in which it is placed. For the grid mode, it is proposed that the microinverter works as current source, and for the island mode it is proposed that the microinverter works as voltage source through the implementations of droop schemes...
This paper presents the analysis, design and simulation of a Photovoltaic energy management system. The proposed system is capable of both grid connected and islanded operation. An operation protocol is proposed to ensure the quality of the energy supply and to minimize the energy losses. A battery bank is connected to the DC-link as an energy storage for islanded operation mode.
This paper presents a new active anti-islanding detection method for distributed power generation systems. This method is based on introducing a disturbance at the inverter output and observing the behaviour of the voltage at the point of common coupling (PCC), which depends on the impedance connected to the PCC in an islanding situation.
This paper presents a comparative study of several speed estimators to implement a torque control loop, in a wind generation system with a three-phase boost rectifier operating in discontinuous conduction mode. The electrical variables measured for speed estimation contain low frequency harmonics of the fundamental frequency of the wind generator, as well as switching frequency components due to the...
The main objective of a soft switching circuit is to reduce the switching losses in a static converter when is switched at high frequency. In this paper is presented a DC link fuzzy logic controller applied to a VSC (voltage source converter). First, is shown the reconstruction of the input membership functions according to current and voltage signals generated in open loop. A simple algorithm is...
