Traditional "central" power plants are inefficient, result in considerable environmental impact, and are typically far from load centres. In contrast, renewable distributed generation plants, with energy sources such as wind and solar, result in increased energy efficiency, reduced carbon emissions, improved power quality and reliability, and reduced line losses. Wind and solar energy system designers face a significant problem in the random, fluctuating nature of these energy sources. However, it is generally observed that wind and sun intensity have a complementary nature; sunny days normally have calm winds, and strong winds often occur on cloudy days, in the evening and at night. Thus it is possible to achieve a more continuous energy supply with much higher generating capacity factors if wind and solar energy systems are combined with storage devices and/or local generating units in what is known as a hybrid setup, solving the problem of energy fluctuations in plant output. To reduce the size of energy storage devices and increase system reliability while maximizing renewable resource use, local distributed energy resources can be coupled to form micro-sources based on smart hybrid renewable energy systems. A micro-source with plug-and-play capability is versatile, as various kinds of energy sources can be added to or removed from the system at any time without affecting the performance of other units. Geographic location, green incentives, fuel costs, electricity price arbitrage, and grid reliability at the location are all involved in the selection of appropriate micro-source building units. In such smart hybrid micro-sources, control and management of power exchange among units is critical to achieve stable operation and optimal utilization of the hybrid system. The proposed research presents a comprehensive plan to address multiple issues related to control and power management of smart coupled hybrid systems for standalone and grid-connected applications.

传统的“中央”发电厂效率低下，导致了相当大的环境影响，并且通常远离负载中心。相比之下，可再生的分布式生成植物，诸如风和太阳能等能源，导致能源效率提高，碳排放减少，提高功率质量和可靠性以及减少线路损失。风能和太阳能系统设计师在这些能源的随机，波动的性质中面临着一个重大问题。但是，通常观察到风和太阳强度具有互补性。晴天通常会有平静的风，强风经常在阴天，傍晚和晚上发生。因此，如果将风能和太阳能系统与存储设备和/或本地生成单元相结合，则可以实现更连续的能源供应，并在所谓的混合设置中结合使用，并解决了能源波动的问题。植物产量。为了减少储能设备的尺寸并提高系统可靠性，同时最大程度地利用可再生资源，可以基于智能混合可再生能源系统形成本地分布式能源资源以形成微型源。具有插件功能的微源是多功能，因为可以随时将各种能源从系统中添加或从系统中删除，而不会影响其他单元的性能。地理位置，绿色激励措施，燃油成本，电价套利和该位置的网格可靠性都参与了适当的微型源建筑单元的选择。在这样的智能混合微型源中，对单元之间的电力交换的控制和管理对于实现混合系统的稳定操作和最佳利用至关重要。拟议的研究提出了一项综合计划，以解决与独立和网格连接应用程序的智能耦合混合系统的控制和电源管理有关的多个问题。
