    Abstract

    Optimization of stand-alone hybrid-renewable power system usually considers the lowest cost of energy. The optimum system configuration for which having the cheapest cost of energy will be suggested into implementation. However, the optimized system is typically valid only for the particular base case condition. It may not be achieved for other specific conditions.This paper presents supply-demand strategy options to enhance system optimization in terms of sizing, cost and energy utilization for stand-alone hybrid-renewable distributed generation as well as CO2 emission reduction. The system complete option consists of a diesel generator, PV module, wind turbine, and battery that supply a village community in Eastern Indonesia with a base of 35 kWh daily and 6.9 kW peak power demands.Simulation involves twosimultaneous scenarios, in which system supplies different loading profile and operating reservevariation.The considered loading profiles are load shifting and valley filling, which are supplied by systems with various operating reserves as percentage power output. It is revealed that the system with 10 PV-Wind turbine operating reserve supplies a load shifting loading pattern shown the least cost of energy with USD 0.369/kWh as well as the highest CO2 emission reduction, amounted 5,5 tons.
