Noval Control Strategies For Distributed Energy Resources
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 6
Abstract
Distributed energy resources, such as solar photo voltaic & diesel generators are used to form microgrids that provide active & reactive power when required. All the generators work in a coordinated manner, if any of them fails to work other will be made equal to the load. This project, mainly proposes three control strategies they are inverter V-F (or P-Q) control, MPPT control and energy storage charging & discharging controls. The controls are done in the grid connected mode as well as in islanded mode conditions. Coordinately solar PV generators are being controlled by using MPPT & V-F are provided by controlling battery storages. This project also shows coordination between distributed energy resources in different irradiance and state of charge constraints of battery. Simulations are done with IEEE 13 bus feeder test system in both the modes such as grid connected and islanded conditions. The proposed method is implemented, trained, and tested using MATLAB and Simpower systems. The results show the effectiveness of the proposed system in controlling three strategies.
