Abstract
Abstract
Phasor measurement unit (PMU) has been widely applied in power grids. For these applications, there is usually a high requirement for data transmission delay and reliability; therefore, short data packets are often used for transmission. Therefore, a downlink communication model for reconfigurable intelligent surface (RIS) assisted multi-PMU is proposed in the paper. We propose a joint optimization problem to maximize the total achievable system rate. Finally, an alternate iterative algorithm based on SCA is proposed. The results show that the proposed algorithm can effectively improve the sum rate.
