   In this Lessons Learned paper, we explore the themes uncovered from a series of facilitated faculty discussions on moving their course back to face to face teaching after the switch to online. The Institute at Anonymous University administrates over 100 faculty whose primary department appointments and teaching assignments are in either engineering or education. Over the last two years, the Institute hosted numerous conversations for faculty members to share experiences, research, and assessments of teaching successes and concerns as they changed instructional modalities, both with the initial move online and the subsequent move back face to face. From these conversations, faculty agree that some things during the move to online instruction, such as office hours, video archives of lectures, and some activities in break-out rooms appear to enhance student learning. Yet data showed that students believed the online experience was less desirable than face to face courses. Now that we have had a near complete semester where most classes were required to be held in the face to face mode, we are hosting conversations with faculty to understand the changes they are now making to their teaching because of the experiences from online instruction.

3. Hybrid AC Transmission System with Back-to-Back Converter Configuration and MTDC Operation Considering PV Energy Integration

   MMC-based back-to-back (B2B) converters are promising for hybrid AC/DC transmission systems when integrating large scale PV sources. This paper proposes a novel configuration for hybrid AC transmission systems with B2B converters and multi-terminal direct current (MTDC) operation which facilitates the integration of PV energy and enhances the system stability and reliability. This is achieved by an advanced interconnection with two operation modes: 1-A bi-directional power flow via AC connections, and 2- Direct active power injection to the MTDC from PV source. Conventional outer, inner and capacitor voltage balancing control systems are utilized in this study for regulating the currents and voltages of B2B converter. Also, The Perturb and observe (P and O) technique is implemented for obtaining maximum power point tracking (MPPT) of the PV generation considering a dc-dc boost converter. The efficacy of this proposed configuration is verified through time-domain simulations carried out by MATLAB/SIMULINK.
