摘要:

生物启发的算法,如遗传算法和模糊推理系统(FIS),目前广泛采用的混合技术在商业和工业环境。在本文中,我们提出了一个有趣的应用模糊遗传算法的范例智能电网。主要目的包括在执行决策的潮流管理任务,在建议的微电网模型配备可再生能源和储能系统,考虑到能源交易的经济利润与主电网。特别是,本研究的重点是应用分层遗传算法(HGA)调整规则库(RB)的模糊推理系统(FIS),试图发现一个最小的模糊规则集的模糊逻辑控制器(FLC)通过执行决策在微电网。HGA原理集中在一个特定的编码方案,基于控制基因和参数基因应用于FIS参数的优化,允许执行RB的结构复杂性的降低。这种方法在下文中将被称为模糊HGA。结果进行了比较与一个简单的方法的基础上,一个经典的模糊遗传算法计划,其中FIS参数和规则权重进行调整,而模糊规则的数量是固定的。实验结果表明,如何模糊HGA方法采用的建议控制器的合成优于经典的模糊GA计划,增加了67%的会计利润在考虑能源交易问题,同时产生一个简单的RB。

英文摘要:

Bio-inspired algorithms like Genetic Algorithms and Fuzzy Inference Systems (FIS) are nowadays widely adopted as hybrid techniques in commercial and industrial environment. In this paper we present an interesting application of the fuzzy-GA paradigm to Smart Grids. The main aim consists in performing decision making for power flow management tasks in the proposed microgrid model equipped by renewable sources and an energy storage system, taking into account the economical profit in energy trading with the main-grid. In particular, this study focuses on the application of a Hierarchical Genetic Algorithm (HGA) for tuning the Rule Base (RB) of a Fuzzy Inference System (FIS), trying to discover a minimal fuzzy rules set in a Fuzzy Logic Controller (FLC) adopted to perform decision making in the microgrid. The HGA rationale focuses on a particular encoding scheme, based on control genes and parametric genes applied to the optimization of the FIS parameters, allowing to perform a reduction in the structural complexity of the RB. This approach will be referred in the following as fuzzy-HGA. Results are compared with a simpler approach based on a classic fuzzy-GA scheme, where both FIS parameters and rule weights are tuned, while the number of fuzzy rules is fixed in advance. Experiments shows how the fuzzy-HGA approach adopted for the synthesis of the proposed controller outperforms the classic fuzzy-GA scheme, increasing the accounting profit by 67\% in the considered energy trading problem yielding at the same time a simpler RB.
