China has one of the most complex interconnected HVAC and HVDC power grids in the world. All of the regional grids of China have implemented a power stability control system which has dramatically improved the stability of the grids... (more)
Assessing the effect of PV generation on distribution system voltages
by Greg Shirek, Milsoft Utility Solutions, USA
 
For solar photovoltaics, different seasons and hours of the day need to be researched to gather and develop best fit insolation curves to assist in the power flows with the distribution system local loads... (more)


What many users don't realise is that the rooftop PV load profile results in unused energy which may be utilised to gain further advantages in effective use of the solar power generated... (more)

Information supplied by DEHN Protection 

Lightning discharges cause field-based and conducted electrical interference. Surges do not only damage PV modules, inverters and their monitoring electronics, but also devices in the building installation... (more)
