摘要：

In an ac/dc hybrid distribution grid (ac/dc HDG), different ac distribution grids are connected through a voltage source converter (VSC)-based dc grid to operate the entire system in a secure and economic manner. This paper presents a decentralized optimal operation approach for running ac/dc HDG which can either work individually or collaborate with each other. Using the analytical target cascading approach, a three-level hierarchy consisting of dc grids, VSC stations and ac grids, is formulated to decompose the operation problem of ac/dc HDG. The obtained subproblems for these grid levels, as well as the interactions between them, are modeled and solved with a nested solution process. The simulation results show the effectiveness of the proposed decentralized approach.
