PROJECT TITLE :

Power Ramp Limitation capabilities of Large PV Power Plants with Active Power Reserves - 2017

ABSTRACT:

Power ramp limitation (PRL) is possible to become a requirement for massive-scale photovoltaic power plants (LPVPPs) so as to allow the increase of PV penetration levels. Particularly in islands with reduced inertia capability, this drawback is additional stringent: high-power ramp can be caused by either fast irradiance changes or other participant generators for example wind power, or loads. In order to compensate for the facility mismatch, LPVPPs should use active power reserve (APR), by either curtailment or auxiliary storage. The paper proposes a PRL control structure for dynamic APR sizing and deployment. The chosen take a look at case is the power system of Puerto Rico (PREPA), modeled using the modified IEEE 12 bus benchmark system, with different levels of PV penetration. It is shown that LPVPP with PRL can effectively reduce the ramping rate of the taking part generators. Considering that the massive area of LPVPPs acts as a filter against quick irradiance changes, the study conjointly reveals the specified plant size for which an auxiliary storage is now not required so as to suits PRL needs-an necessary economical facet.
