Abstract
Renewable energy technologies can not only help in mitigating the greenhouse gas (GHG) emissions but it can also be very useful for electricity generation at remote locations, where no other means of power are available. The present study focuses on the techno-economic optimum design of a small hybrid renewable energy system (HRES) consisting of wind-solar as primary energy sources. The HRES was modelled for a remote island (Deokjeok-do Island, South Korea) using real electricity consumption data for one complete year. A daily mean load of 24,720 kWh was entered at Deokjeok-do Island with a peak load of 2291.54 kW. Average annual values of wind speed and daily solar radiations were estimated to be 3.6 m/s (10 m height) and 4.13 kWh/m2, respectively. A total of 8760 simulations were performed to achieve the hourly load demand of the mentioned island. In order to deal with the surplus and electricity deficit, two different types of energy storage systems (ESS) were modelled i.e., battery and pumped hydro storage (PHS). Four different HRESs were also evaluated as the most suitable based on levelized cost of energy (LCOE) and net present cost (NPC). A detailed economic break-down of each component and the impact of different sensitivity variables on decision making have also been discussed in detail.
Highlights
With the rapid increase in the population of the world over the last few decades, it has become a serious challenge for governments and energy policymakers to fulfil the electricity requirements of the majority of the people
This section will present the analysis on the basis of detailed technical and economic calculations and characteristics of the most ideal energy systems best-suited for Deokjeok-do
Out of all the feasible system solutions (232,683), two systems were selected as the most appropriate choice based on lowest possible net present cost (NPC) and lowest possible levelized cost of energy (LCOE)
Summary
With the rapid increase in the population of the world over the last few decades, it has become a serious challenge for governments and energy policymakers to fulfil the electricity requirements of the majority of the people. Jibran et al [9] surveyed the biomass capacity of Pakistan and expressed that biomass can produce 24% of the total electricity demand of the country They thought about biomasses, for instance, city strong waste (MSW), bagasse and local creatures compost in their assessment. Binayak B. et al [10] thought about an extraordinarily commendable model of HRES for town zap, containing wind-PV-hydro as fundamental vitality sources. They showed that presenting such HRESs at remote zones can be monetarily more affordable when contrasted with customary assets of vitality, for example, atomic. Jameel A. et al [12] analyzed the HRES involving wind-PV-biomass as fundamental vitality hotspots for a network in Pakistan called the Kallar Kahar. The examination was driven for various conditions and analysts proposed the foundation of HRES near recently referenced site dependent on strong moderate financial outcomes
