This research presents a technical simulation and economic model of three small-scale technical alternatives supplying a typical rural homestead electricity load: a 15kVA wood gasification unit coupled to a 6kWe modified grid-connected petrol generator; the same system operating as a stand-alone...

This paper presents a mixed-integer linear programming (MILP) super-structure model for the optimal design of distributed energy generation systems that satisfy the heating and power demand at the level of a small neighborhood. The objective is the optimal selection of the system components...

This paper presents a passive islanding detection method for wind turbines. The proposed method is based on voltage measurements and processing of this voltage with a discrete wavelet transform. This method detects the islanding conditions with the analysis of Daubiches wavelets. The studies...

Nowadays the use of distributed generating systems, which use a renewable energy source, has experienced a fast development. Moreover their intrinsic intermittent nature can be overcome using hybrid systems which combine more energy sources. This paper discusses the main topologies which can be...

Microgrids are LV or MV electric networks which utilize various distributed generators (DG) to serve local loads. In this paper, dynamic models of the main distributed generators including photovoltaic (PV) cell, wind turbine, hydro turbine as well as the equivalent power electronic interfaces,...

This paper proposes a decentralized control strategy for higher penetration of photovoltaic (PV) units without violating system operating constraints. A systematic procedure is developed and a robust controller is designed to ensure both dynamic voltage and transient stability for a specific PV...
