Multiobjective optimized rural microgrid with hybrid power sources

Abstract

In this research study, an exhaustive review of literature has been conducted. Based on this review, diverse configurations of standalone hybrid energy microgrids, comprising various combinations of renewable energy sources, diesel generator, and batteries, have been analysed for their cost-effectiveness and reliability. Mathematical model of system components and design parameters have been implemented in four different hybrid micro grid for remote rural area in Gujarat, India. Performance assessment of proposed Load Following (LF) and Cycle Charging (CC) dispatched strategies on four different combination of standalone hybrid energy system Micro grid were investigated and simulated. Based on assessment and simulations we find the best optimal Standalone Solar PV, Diesel with Li-Ion Battery hybrid micro grid under the Cycle charging (CC) strategy consisted of a 530 kW Solar PV, a diesel generator (DG) with a 50 kW capacity, 484 batteries (LI), and a 101 kW power converter. The system yielded an NPC of $ 699793 and COE of 0.0879 $/kWh, which lower than all of cases utilizing the LF and CC strategies, respectively. newlineA sensitivity analysis has been performed on a standalone Solar PV, Diesel with Li-Ion Battery hybrid microgrid, taking into account Load Following (LF) and Cycle Charging (CC) dispatch strategies. This analysis focuses on two critical sensitivity parameters: diesel price and Capacity Shortage (kWh). newlineThe impact of utilizing lead-acid (LA) and lithium-ion (LI) batteries on the performance of a Standalone Solar PV, Diesel with Li-Ion Battery hybrid microgrid, employing Load Following (LF) and Cycle Charging (CC) dispatched strategies, has been evaluated. It is found that the Standalone Solar PV, Diesel with Li-Ion Battery hybrid micro grid using CC Strategy has lowest NPC and COE are as $ 699793 and 0.0879 $/kWh, respectively. The findings reveal that employing Li-Ion batteries yields the most optimal solutions with Cycle Charging (CC) and Load Following (LF) strategies when compared to Lead-Acid
