应用风光互补系统（WPVHS），以满足农村地区的电力需求具有很大的潜力，因为这些可以提供电力的成本效益的方式。但是根据实施者和项目设计者的观点，选址是WPVHS成功的重要因素。为了解决这一问题，开发了一种基于地理信息系统的方法，以选择特定区域的技术和财政上可行的地点。该方法适用于两个不同国家的两个不同地区，即没有电力覆盖和有电力覆盖的地区：印度尼西亚罗特岛的罗特登加和潘泰巴鲁区以及越南的老街省。在这两种情况下，该方法能够找到潜在的资源密度。在罗特岛，五个网站被发现有技术潜力的WPVHS，而在老街省没有发现合适的网站。根据财务分析，该方法选择的最合适的地点是巴鲁潘泰地区的Oeledo德萨，该地区已在e7安装了风能光伏系统。还进行了情景分析，以表明该方法可以应用于解决各种限制（例如，提供激励，降低O&M成本，区域/位置的需求等）。由于模型和结果都是基于GIS的，因此规划者和项目开发人员可以很容易地将结果可视化。主要目标：这项研究的主要目的是开发一个模型，利用地理信息系统评估安装风力/光电混合系统的地点的可行性，以实现分散式农村电气化。背景资料：由于新技术的迅速发展，利用可再生能源实现农村电气化在财政上变得可行[1]。风光互补系统（WPVHS）的应用在满足农村地区的电力需求方面具有巨大潜力，因为这些系统可以以具有成本效益的方式提供电力[2]。一项研究表明，这些系统最大限度地减少了对环境的影响，并提高了供电的可靠性[3]。因此，风光互补系统（WPVHS）将是一个合适的选择，分散的农村电气化。然而，风-光混合系统的成功主要取决于适当选择特定的场地条件，而WPVHS的成功取决于适当的场地选择[4]。理由：可再生能源资源取决于地理位置以及一天中的时间。因此，电力消耗应在距离生产现场有限的距离内进行。可再生能源供应的识别和估计以及电力需求概况的估计可以给出一个地区的电力需求和资源的总体方案，可以在此基础上制定当地的能源计划。这可以很容易地用地理信息系统（GIS）来说明，这是一个有用的工具，用于了解与能源有关的广泛问题的地理背景，特别是电力需求和一个位置的资源的可行性[5]。数据来源：E7印度尼西亚项目，由e7企业网络、印度尼西亚计量部门、桑迪亚国家实验室、国家可再生能源实验室开发和启动的项目
Application of Wind-PV hybrid system (WPVHS) has great potential to meet the electricity needs of rural areas as these could provide electricity in a cost effective way. But according to the implementers and project designers site selection is very important factor for success of WPVHS. To address this issue, a GIS based method has been developed to select technically and financially feasible sites of a given region. The methodology was applied in two different areas without and with electricity coverage in two different countries: Rote Tengah and Pantai Baru districts of Rote Island, Indonesia and Lao Cai province of Vietnam. In both cases, the methodology is able to find the potential resource density. In Rote Island, five sites were found to have technical potential of WPVHS, whereas, in Lao Cai province no sites were found suitable. From the financial analysis the most suitable site selected by the method is Oeledo desa of Pantai Baru district, where a wind-PV system has been installed by e7. A scenario analysis was also carried out to show that the methodology can be applied addressing various constraints (e.g. providing incentive, reducing O&M cost, demand of the region/location etc.). As the model and the results are based on GIS, it is easy for the planners and project developers to visualize the results. Main Objectives: The main objective of the study is to develop a model to assess the feasibility of a site for the installation of wind/PV hybrid systems for decentralized rural electrification using a Geographical Information System (GIS). Background Information: Utilization of renewable energy resources is becoming financially feasible for rural electrification due to the rapid development of the new technologies [1]. Application of Wind-PV hybrid system (WPVHS) has great potential to meet the electricity needs of rural areas as these could provide electricity in a cost effective way [2]. A study shows that these systems minimize the environmental impacts and increase the reliability of power supply [3]. Therefore, wind-PV hybrid system (WPVHS) would be a suitable option for decentralized rural electrification. However, success of a wind-PV hybrid system would mostly depend on the appropriate selection of the site specific conditions and the success of WPVHS depends on appropriate site selection [4]. Rational: RE resources are depends on geographical location as well as the time of the day. Therefore, electricity consumption should take place within limited distance from the production site. Identification and estimation of RE supply and estimation of electricity demand profile could give a total scenario of electricity demand and resource of an area based on which local energy plan could be made. This can be easily illustrated using Geographic Information System (GIS) which is a useful tool for understanding the geographic context of a wide range of issues relevant to energy, especially electricity demand and feasibility of the resources of a location [5].
