Dimming of street lighting systems with current reactive energy control

The report analyzes the behavior of the lighting load for street lighting during dimming. There are classical installations with HLVH and new - with LED lights. For both types of equipment, the power factor becomes worse when dimmed - when dimming from 100 to 50% for the first $0.95 \gt$ PF $\gt0.6$; for the second $-0.96 \gt$ PF $\gt$ -0.8. And if in the first case the increase in the price of active energy is not high (sanctions in percent of the so-called cosine-fi tariff if PF $\lt0.9)$, in the case of the second type the reactive energy is sold by the electricity distribution companies at the same cost as the active. The question is how to prevent the payment of reactive energy as active?
