Abstract

Droop control is a load sharing strategy applied in conventional power systems. In this paper, droop control strategy has been adopted for the generators in a remote area power supply (RAPS) system in order to share active and reactive power load based on the rated capacities of the generators. Different characteristics of conventional and inverter-based energy resources make it difficult to share load in proportion to the rated capacities of the generators in a RAPS system. Therefore, this paper investigates the load sharing performance of different combinations of conventional and inverter-based energy resources in RAPS systems. The study scenarios investigated in this study comprised of conventional energy resources, inverter-based energy resources, and both conventional and inverter-based energy resources. Simulation results have illustrated the effectiveness of droop control strategy to share load among conventional and inverter-based energy resources in a RAPS system. Furthermore, due to different characteristics of generators, power sharing performance has impaired, in particular, in RAPS systems consisting of both conventional and inverter-based generators compared to the RAPS systems with generators of the same type.

基于下垂控制的远程电力系统可再生和不可再生能源负荷共享管理方法

下垂控制是一种应用于传统电力系统的负荷分担策略。本文针对偏远地区供电系统中的发电机，根据其额定容量，采用下垂控制策略实现有功负荷和无功负荷的共享。传统能源和基于逆变器的能源的不同特性使得在RAPS系统中很难按比例分担发电机的额定容量。因此，本文研究了RAPS系统中传统能源和基于逆变器的能源的不同组合的负荷分担性能。本研究调查的研究场景包括常规能源、基于逆变器的能源、常规能源和基于逆变器的能源。仿真结果验证了下垂控制策略在RAPS系统中实现常规能源和逆变器能源负荷共享的有效性。此外，由于发电机的不同特性，与具有相同类型发电机的RAPS系统相比，由传统发电机和基于逆变器的发电机组成的RAPS系统的功率共享性能受到损害。
