Zonal pricing is a well-suited mechanism to incentivize grid-supporting\nbehavior of profit-maximizing producers and consumers operating on a\nlarge-scale power system. In zonal electricity markets, local system operators\ncreate individual price zones, which provide appropriate price signals\ndepending on local grid conditions such as an excess or shortage of electrical\nenergy in certain regions. In this paper, a real-time zonal pricing controller\nfor AC power networks is presented that ensures frequency and voltage stability\nas well as Pareto efficiency of the resulting closed-loop equilibria. Based on\na dynamic network model that takes line losses and power exchange with adjacent\nprice zones into account, distributed continuous-time control laws are derived\nwhich require only neighbor-to-neighbor communication. Application to a\nreal-time congestion management strategy illustrates how spatially and\ntemporally differentiated prices enable grid-supportive operation of the\nparticipants without interventions by a superordinate control authority.\nEffectiveness of different zonal pricing concepts compared to an isolated grid\noperation is demonstrated through simulations on the IEEE-57 bus system.\n
