Responding to the fact that large traditional generators are being retired while the amount of renewable energy sources is increasing, the Planning Committee for PJM Interconnection recently approved a plan to "explore whether to require renewables such as solar PV to install enhanced or 'smart' inverters that can produce and absorb reactive power in addition to inverting DC power to AC," RTO Insider reports. Although it is not a current problem for PJM, renewable power generators equipped with smart inverters in Great Britain and Germany improve grid reliability by allowing "renewable generators to stay on line despite low voltages and fluctuating frequencies," while also reducing the flickering that "can occur with solar generators on days of mixed sun and clouds," the article said.
