Integrated Solar PV-Battery and Micro-Hydro Based Low-Voltage Autonomous DC Microgrid for Rural Electrification

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 microhydro 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.

“…An autonomous DC system with a Photovoltaic (PV), Batteries Energy Storage System (BESS), and Micro Hydro (MH) is introduced to reduce costs and increase reliability) Strategy (PMS) [1]. An autonomous system, PV/Wind Turbine (WT), Supper condenser Storage System (SCSS), BESS, and hydrogen tank is presented to minimizing costs and increasing reliability, the BESS is reduced to 56% and the level of hydrogen is increased to 98% [2].…”
