Implementing HVDC Line Modeling in MOST Simulation Environment for Multi-period Optimal Power Flow
This paper proposes an approach to integrate HVDC (High Voltage Direct Current) line models in the open access tool MOST. MOST is an extension of the well-known Matpower simulation environment, and it can solve multiperiod linearized optimal power flow ...
