Hybrid Energy Storage Supported Backup For Photovoltaic Based Microgrid
Journal Title: IOSR Journals (IOSR Journal of Electrical and Electronics Engineering) - Year 2018, Vol 13, Issue 4
Abstract
The proposed operational strategy is mainly focused on using an appropriate energy management and control strategies toimprove the operation of an islanded microgrid, formed by photovoltaic (PV) system, SMES-batteries and loads. This control strategy is to achieve decentralized power management of a PV/battery/Fuel cell hybrid unit in a droop-controlled islanded microgrid. In contrast to the common approach of controlling the PV unit as a current source, in the proposed strategy, the PV unit is controlled as a voltage source that follows a multi-segment adaptive powercharacteristic curve. The proposed power characteristics, of the hybrid unit and of the whole microgrid, adapt autonomously to the microgrid operating conditions so that the hybrid unit may supply the maximum PV power, match the load, and/or charge the battery, while maintaining the power balance in the microgrid and respecting the battery state-of-charge limits. These features are achieved without relying on a central management system and communications, as most of the existing algorithms do. The simulations andcomparisons among the SMES-based, BES-based and HES-basedDVR schemes have demonstrated that the HES-based DVRscheme integrates the merits of fast response speed and highpower density from the SMES-based scheme and the merits of lowcapital cost and high energy density from the BES-based scheme.
