Narrative:

During approach into ZZZ we encountered icing and had to use wing and cowl ai systems. Fadec kept the power up with engines at idle. I forgot to account for this; first approach this season with wing ai and fadec. I had a difficult time slowing down to configure the aircraft. I opted to level off to configure. This caused us to be high on the approach so increased descent and had autopilot off. We became task saturated with configuring and checklists and I ended up well below the glide path. At this point we were out of the clouds. Since I could the runway and obstacles; I immediately started a correction to the glide path. At the same time we received a call from tower or approach advising us we were low which we responded that we were correcting. Once reestablished we continued the approach uneventfully. PF (pilot flying) visually detected and received a call from ATC. Forgot that fadec keeps a higher power at idle with wing ai on which caused task saturation when trying to configure. Corrected position on the glide path and continued the approach. Remind crews about fadec power with wing ai on especially with winter here.

Title: CRJ900 Captain reported while using wing and cowl anti ice; FADEC kept power up making it difficult to slow and configure; resulting in excursions above and below the glideslope.

Narrative: During approach into ZZZ we encountered icing and had to use Wing and Cowl AI systems. FADEC kept the power up with engines at idle. I forgot to account for this; first approach this season with Wing AI and FADEC. I had a difficult time slowing down to configure the aircraft. I opted to level off to configure.
