| description | Hybrid renewable power systems can provide a viable solution to electrification of isolated areas. Design of isolated hybrid system primarily focuses on optimal sizing of the supply components for desired reliability and a given load profile of the area. Optimally sizing supply system without considering the available end use options, does not guarantee the cost-effective isolated hybrid system for a desired reliability. The paper presents a generalized methodology for sizing the isolated hybrid systems considering a prior demand and supply side options. Demand side options available for different end use loads and their potential impact on hybrid system sizing, is analysed in this study Aggregated consumption model is developed for different sectors (residential, agriculture, community and small-scale commercial) based on the technical ratings and time of use patterns of different end use loads. The developed methodology is illustrated for a typical isolated area (24 hour supply) and existing electrified village case study (4 hour supply). Energy conservation DSM options for different end use loads are sequentially integrated with supply side options for optimally sizing the system. Feasible sizing solution in terms of reduced system ratings and capital cost is obtained for kWh reduction of energy service when compared to without DSM case. For case of typical isolated area, with the selected DSM options, PV ratings reduced by 59 %, battery rating by 60 %, and annual life cycle cost by 56 % compared to No DSM case. This paper highlights the importance of considering the demand side options evaluation with supply side for design and planning of isolated hybrid systems. |
