Four-dimension resource scheduling solution in new energy power plants

基于正交频分复用(OFDM)的动态资源调度(DBA),被认为是一种解决新能源电厂通信资源调度不足的很有前景的重要备选方案,可以满足不同用户的时间、地点以及资源需求。文中提出了一种在媒体访问控制层(MAC)解决新能源电厂上行通信的OFDM-DBA调度算法。为了有效地利用电厂通信资源,在提出的DBA算法中采用了四维空间的调度。四个维度代表频率域、时间域、调制格式和功率分配。该算法具有很强的灵活性。仿真结果和分析表明,该算法能有效地利用电厂通信带宽,使系统具有很强的节能效果。

Dynamic bandwidth allocation( DBA),which is based on Orthogonal frequency division multiplexing( OFDM),has been considered a promising solution to meet the insufficient of communication resource scheduling in new energy power plants for different users in terms of the time,location and resource requirements. In this paper,an OFDM-DBA scheduling algorithm for at medium access control( MAC) layer to solve uplink transmission of new energy power plant. In order to utilize the bandwidth efficiently,four-dimension space scheduling is adopted in the proposed DBA algorithm.Four-dimension stand for frequency domains,time domains,modulation formats and power allocations.The algorithm is quite flexible. Simulation results and analysis show that the proposed algorithm can efficiently utilize the power plants communication bandwidth and make the system highly energy-efficient.
