Novel Control And Harmonics Impact Of Pv Solar Farms, Byomakesh Das
Novel Control And Harmonics Impact Of Pv Solar Farms, Byomakesh Das
Electronic Thesis and Dissertation Repository
This thesis presents a novel application of Photovoltaic (PV) solar system inverter, both during night and day, as a dynamic reactive power compensator STATCOM. This technology, termed PV-STATCOM, is designed and developed for power factor correction in the networks of two utilities: Bluewater Power, Sarnia, and London Hydro. This thesis further describes for the first time, the harmonic impact studies on a utility distribution network in presence of the largest PV solar farm in Canada.
This novel utilization of a PV-STATCOM for power factor correction of induction motor loads is demonstrated with (i) electromagnetic transient simulation in EMTDC/PSCAD software, (ii) …

Novel Controls Of Photovoltaic (Pv) Solar Farms, Shah Arifur Rahman
Electronic Thesis and Dissertation Repository
Solar Farms are absolutely idle in the night and even during daytime operate below capacity in early mornings and late afternoons. Thus, the entire expensive asset of solar farms remains highly unutilized. This thesis presents novel technologies for utilization of PV solar farm inverter in nighttime for providing multiple benefits to power systems, as well as accomplishing the same objectives during the daytime from the inverter capacity left after production of real power. The new technology transforms a solar farm inverter functionally into a dynamic reactive power compensator known as STATCOM, and termed PV-STATCOM.
A novel coordinated control of PV-STATCOMs …

Subsynchronous Resonance In Wind Farms, Akshaya Kumar Moharana
Electronic Thesis and Dissertation Repository
Large-scale integration of wind farms in transmission networks has led to several challenges; one of which is the need for increased transmission capacity to transport a bulk amount of wind power. Series compensation is an established means of enhancing the power transfer capability of existing transmission lines and is being increasingly considered for integrating large wind power plants. However, series compensated transmission lines may cause subsynchronous resonance (SSR) in turbine-generators, which can lead to electrical instability at subsynchronous frequencies and potential turbine-generator shaft failures.
This thesis deals primarily with the potential of subsynchronous resonance in induction generator based wind farms …
