Today, the microgrid is not a new concept, and its diverse benefits for the grid and also consumers have been proven. One of the effective ways to enhance penetration level of the microgrids is to improve economic affordability. This can be achieved by defining an optimal investment plan which has been studied for the several past decades. Previous researches have been proposed a model which used a set of typical values as input parameters of the components. As a result, the optimization results may not be fully implementable in practice. In this regard, this paper proposes a new planning model for a hybrid AC–DCmicrogrid which selects the best technology from a set of commercial models already available in the market in addition to optimally selecting the size (number) of each equipment. Among the microgrid equipment, this capability is considered for storage batteries and wind turbines considering their variety of parameters and market models. The proposed model, while linear, takes into account the various parameters of the equipment in addition to the reliability and emission constraints. Results of implementing the proposed model on a test case demonstrated that outputs of the proposed model are more applicable to real practical projects.

如今，微电网已经不是一个新概念，它已经为电网以及消费者带来了多种好处。提高微电网渗透水平的有效方法之一是提高经济承​​受能力。这可以通过定义最佳的投资计划来实现，该计划已经研究了数十年。先前的研究已经提出了一种模型，该模型使用一组典型值作为组件的输入参数。结果，优化结果在实践中可能无法完全实现。在这方面，本文提出了一种用于AC-DC混合微电网的新计划模型，该模型除了可以最佳选择每个设备的尺寸（数量）之外，还从市场上已有的一系列商业模型中选择最佳技术。在微电网设备中，考虑到它们的各种参数和市场模型，这种能力被考虑用于蓄电池和风力涡轮机。所提出的模型虽然是线性的，但除了可靠性和排放限制外，还考虑了设备的各种参数。在一个测试用例上实现建议的模型的结果表明，建议的模型的输出更适用于实际的实际项目。
