With the proliferation of alternate power sources such as fuel cells system in the distributed power system, inverter is the key component of the system. Parallel inverter systems can be designed to have the advantages to improve output power and reliability etc. In order to share the load and restrain circumfluence, A power sharing control technique for inverter parallel operation is described in...
Grid-connected inverters are widely used in the distribution generation (DG) systems for the conversion of renewable energies. These inverters are usually connected to the utility grid through LCL filter to reduce the current harmonics injected to the grid. A LCL network, which can achieve reduced levels of harmonic distortion at low switching frequencies with less inductance, is a good alternative...
This paper presents a two-point estimate (TPE) based method for probabilistic analysis of small signal stability of a microgrid (MG) considering uncertainties. The uncertainties may arise from different sources as load demand or generation unit outages. This method combines the TPE method and probabilistic small signal stability analysis. Stability indices and the judgment of unstable types for microgrid's...
The research progress in the fields of distributed generation (DG) and micro-grid (MG) are summarized in this paper, which mainly focuses on the schemes of DG islanding detection, DG's relay protection as well as the control strategy of converters. It is beneficial to realize the situation in these aspects and to know the improvements can be made in the future.
