Abstract

The decreasing cost and simplicity in deployment of Solar-Photovoltaic (SPV) system have led to its penetration extended to the highly remote/rural areas. The SPV systems possessing non-dispatchable characteristics are typically deployed in the form of a DC microgrid or an AC microgrid in such areas. For rural electrification, a low voltage DC microgrid with SPV source suitably integrated with local resources like wind or micro-hydro generation plant supported with energy storage becomes highly desirable to enhance the availability of power throughout the day. This paper presents implementation and control of an autonomous Integrated SPV-battery and Micro-hydro based DC microgrid (DC-MG) meeting the need of electrical energy in remote rural areas. This paper proposes the hierarchical power control which enhances the operational reliability and flexibility.
基于太阳能光伏电池和微水电的农村电气化集成低压自主直流微电网
太阳能光伏(SPV)系统成本的降低和部署的简单性使其渗透扩展到高度偏远的农村地区。SPV系统具有不可调度特性,通常以直流微电网或交流微电网的形式部署在这些地区。对于农村电气化,一个具有SPV电源的低压直流微电网与当地资源(如风力或微型水力发电厂)适当整合,并支持储能,以提高全天的电力可用性是非常可取的。本文介绍了一种满足偏远农村地区电力需求的基于spv -电池和微水电的自主集成直流微电网(DC- mg)的实现和控制。提出了分层功率控制,提高了系统运行的可靠性和灵活性。
