This paper is concerned with the promising benefits of the incorporation of demand response (DR) scheme in residential end-users, but considering the AC distribution network's constraints and several retail companies or Local Service Entities (LSEs) participating in the retail market. This residential DR is modeled as an OPF problem run by the Operator of the distribution network, with the aggregated information collected by each retail company from their clients. We use a simple model and formulate the problem as a dynamic program that maximizes social welfare. The primal-dual method used to decouple some constraints and optimize the system, preserves the integrity of the private information of each participant and captures its preferences and constraints.

In this paper, the linear minimum mean square error beamformers are designed for relay-assisted cloud radio access network (C-RAN). In C-RAN, the remote radio units are separated from the baseband units to save energy cost. To further enhance network coverage, it is a good choice to duly arrange relay nodes. Regrading the per-antenna power constraints at both the relay nodes and the remote radio heads (RRHs), the beamformer matrices at the relay nodes and RRHs are jointly optimized for the relay assisted C-RAN. Since the considered problem is a non-convex optimization problem and is with multiple variables, it is in general very hard to solve. To make the design suitable for C-RAN exploiting the problem structure, two novel decomposition algorithms are proposed. One algorithm is mainly carried out at the RRHs, another is mainly performed at the relay node. Finally in the simulations, the performance of the proposed algorithms is demonstrated.
