This article examines a cooperative communication network in the smart grid, optimizing the transmission power allocation of relays to reduce errors and costs. By introducing a two-layer game model and iterative algorithm, the total costs of utility companies can be minimized.
The packet loss during transmission of load control commands can lead to regulation errors in the smart grid and further increase the cost of utility companies due to the purchase of additional automatic generation control services. This article considers a cooperative communication network consisting of multiple data aggregation units (DAUs) and multiple relays in smart grid, and each relay can forward data for all DAUs. We optimize the transmission power allocation of the relays to reduce the demand-side regulation errors and the cost of utility companies. However, additional cost is incurred due to the rental of relay in commercial networks. In order to minimize the total costs of utility companies, a two-layer game model is proposed and an iterative algorithm is developed. Simulation results show that the cost of utility companies can be reduced under the proposed scheme.
