Solar Photovoltaic Inverters and Ride-Through Capability
In study after study, we (Pterra) are encountering this seemingly mounting issue of ride-through capability in solar photovoltaic (“PV”) inverters. For now, the matter is isolated to frequency ride-through in small grids such as those that may be found in the Hawaiian islands. However, there is potential for this to be critical in even larger systems as the number of inverter-based PV arrays interconnecting to existing distribution and transmission systems increases.

Can wind turbines and solar inverters contribute to frequency control?
Renewable energy resources such as solar and wind, produce power in a manner that generally does not contribute to frequency control of interconnected power systems. However, both wind turbines and solar inverters have the important characteristic of fast, programmable controls. The question then comes up: Is it possible for these power sources to participate in frequency control response of interconnections? Continue reading
Integrating Solar PV Power with Existing Distribution Circuits; Part 1
A wave of new solar photovoltaic (“PV”) installations for power generation is hitting many distribution circuits around the country. These installations are typically in the range of 10-2000 kW and comprise of a set of solar PV arrays or trays … Continue reading

Transient Overvoltages in Wind Farms, and a Case Study
In various Blogs on this site, we have talked about unique technical issues associated with integrating wind farms into existing grids. This Blog now addresses the matter of transient overvoltages, or TOV, specifically with respect to potential risks to customers … Continue reading

Transmission bases for sizing wind and solar projects
Unlike base load power plants such as nuclear and some coal plants which operate near full capacity for days at a time, solar photovoltaic (PV) and wind farms are variable resources whose output is dependent on the minute-by-minute change in … Continue reading
Report from the 2011 PSLF Users’ Group Meeting
by Ric Austria If only for this one new feature, the trip to attend the meeting (held April 28-29 in sunny Orlando, Florida) was worth it. The new feature is … PSLF now allows “continuous” tap solutions for phase angle … Continue reading

Distributed Generation: Interconnection Steady State Impact
Jingjia Chen, Ketut Dartawan, Ricardo Austria Distributed generators (DGs) are small generating units that are connected to the distribution network at voltages below 69 kV. DG units usually have capacities of 10MW or less, and are based on different energy … Continue reading
Incentives for Solar Power Abound
No doubt that solar power is a rising component of the world’s energy supply. The main incentives for photovoltaic type PV are improving technology, dropping manufacturing prices and continuing government support through tax credits and renewable portfolios. We’ll keep a close … Continue reading
