Abstract

ABSTRACT Solar based microgrids provide an environmentally benign alternative to conventional generation. However, their capital intensive structure and variability compels comprehensive examination of planning scenarios. This paper presents a bi-stage planning framework for a solar-battery microgrid. In the first stage of planning, sizing is carried out for autonomous operation. The second stage extends analysis to grid connected mode wherein four cases of microgrid operation are investigated. The analysis involves techno-socio-economic evaluation of constrained and unconstrained power flow. The parameters such as risk state probability, unmet load fraction, levelized cost of energy and social cost of carbon are used to evaluate and compare different cases for a solar-battery based microgrid located in Jaisalmer, Rajasthan, India. The results demonstrate that storage integration is essential for sustaining reliability in autonomous operation of microgrid. It can be inferred from the results that permitting reverse power flow renders considerable economic benefits and fetches lowest cost.

采用技术-社会经济评价的太阳能电池微电网双阶段规划框架

基于太阳能的微电网为传统发电提供了一种环保的替代方案。然而，它们的资本密集结构和可变性迫使对规划情景进行全面检查。本文提出了一个太阳能电池微电网的双阶段规划框架。在规划的第一阶段，进行自主操作的分级。第二阶段将分析扩展到并网模式，其中研究了四个微网运行案例。分析涉及有约束和无约束潮流的技术-社会经济评价。采用风险状态概率、未满足负荷比例、能源平准化成本和碳社会成本等参数，对印度拉贾斯坦邦斋萨尔梅尔太阳能电池微电网的不同案例进行了评估和比较。结果表明，储能一体化是保证微电网自主运行可靠性的关键。从结果可以推断，允许反向潮流可以获得可观的经济效益和最低的成本。
