We analyze pricing mechanisms in electricity markets with AC power flowequations that define a nonconvex feasible set for the economic dispatchproblem. Specifically, we consider two possible pricing schemes. The firstamong these prices are derived from Lagrange multipliers that satisfyKarush-Kuhn-Tucker conditions for local optimality of the nonconvex marketclearing problem. The second is derived from optimal dual multipliers of theconvex semidefinite programming (SDP) based relaxation of the market clearingproblem. Relationships between these prices, their revenue adequacy and marketequilibrium properties are derived and compared. The SDP prices are shown toequal distribution locational marginal prices derived with second-order conicrelaxations of power flow equations over radial distribution networks. Weillustrate our theoretical findings through numerical experiments.
