The world energy system is slowly turning toward renewable energy resources. The concepts of distributed generation and microgrids are into implementation but still in the deliberation phase. The benefits of a small power system are its cost, easy installation, integration of renewable with non-renewable energy sources, and switching between on-grid/off-grid modes. Renewable energy-based microgrids have the main challenges of maintaining their frequency-voltage characteristics and the system becomes more complex when they are interconnected. These sources being intermittent in nature need to be supported by other resources like diesel/biogas-based system such that at time of small variation in load or natural sources (wind/solar), the power requirement is met through the support provided by diesel/biogas-based systems. Also, the controller should be fast enough to minimize the changes such that the system reaches a steady state. In this paper, renewable-based rural microgrids consisting of Wind, Solar, and Biogas are modeled and interconnected through the Low voltage DC line. Control approach has been developed in such a way that whenever there is a disturbance in the system due to an increase/decrease in load or input to the renewable energy sources the biogas-based system of individual microgrid increases/decreases its generation to support the system requirement. No extra power is drawn through the interconnecting network. Modeling of the system and its dynamic Study has been carried out in Matlab/Simulink.

世界能源系统正在慢慢转向可再生能源。分布式发电和微电网的概念正在实施，但仍处于审议阶段。小型电力系统的优势在于其成本低、易于安装、可再生能源与不可再生能源的整合以及并网/离网模式之间的切换。基于可再生能源的微电网面临的主要挑战是保持其频率-电压特性，并且当它们互连时系统变得更加复杂。这些资源在自然界中是间歇性的，需要其他资源（例如柴油/沼气系统）的支持，以便在负载或自然资源（风能/太阳能）变化很小时，通过柴油/沼气提供的支持来满足电力需求。基于沼气的系统。还，控制器应该足够快以最小化变化，从而使系统达到稳定状态。在本文中，由风能、太阳能和沼气组成的基于可再生能源的农村微电网被建模并通过低压直流线路互连。控制方法的开发方式是，每当系统因负载增加/减少或可再生能源输入而出现干扰时，基于沼气的单个微电网系统都会增加/减少其发电量以支持系统要求。通过互连网络不会消耗额外的电力。系统建模及其动态研究已在 Matlab/Simulink 中进行。和沼气通过低压直流线路建模和互连。控制方法的开发方式是，每当系统因负载增加/减少或可再生能源输入而出现干扰时，基于沼气的单个微电网系统都会增加/减少其发电量以支持系统要求。通过互连网络不会消耗额外的电力。系统建模及其动态研究已在 Matlab/Simulink 中进行。和沼气通过低压直流线路建模和互连。控制方法的开发方式是，每当系统因负载增加/减少或可再生能源输入而出现干扰时，基于沼气的单个微电网系统都会增加/减少其发电量以支持系统要求。通过互连网络不会消耗额外的电力。系统建模及其动态研究已在 Matlab/Simulink 中进行。控制方法的开发方式是，每当系统因负载增加/减少或可再生能源输入而出现干扰时，基于沼气的单个微电网系统都会增加/减少其发电量以支持系统要求。通过互连网络不会消耗额外的电力。系统建模及其动态研究已在 Matlab/Simulink 中进行。控制方法的开发方式是，每当系统因负载增加/减少或可再生能源输入而出现干扰时，基于沼气的单个微电网系统都会增加/减少其发电量以支持系统要求。通过互连网络不会消耗额外的电力。系统建模及其动态研究已在 Matlab/Simulink 中进行。
