The present use of renewable energy sources (RES) will increase strongly in the future. The actual systems of electricity, gas and heat supply have grown over the last 100 years and it was designed to transmit the energy from large, central power plants to distributed con-sumers. To handle a large number of fluctuating feed-in by RES it must not only be rein-forced but transformed fundamentally. A constantly recurring adjustment is only a sympto-matic patching of vulnerabilities. To ensure a proper transformation, a referring target must be set. The new Loop-Circle-Arc-theory (LoCA) finally offers a method to design and evaluate this transformation target.The LoCA-theory combines cellular design, fractal organization and joint energy carriers. The cellular design understands energetic balance groups as self-organizing and self-optimizing energy cells. The fractal organization describes the self-similarity between the whole and its individual parts. Energy carriers are not further considered and traded separately, but they rather complement each other. The joint of electricity, gas and heat increases synergy ef-fects.The central element in the LoCA-theory, which is used again and again, is the energy cell, which is called Cell from this point onwards. Each Cell has exactly one Port, one Source, one Storage, one Converter and one Sink. The Cell provides algorithms for self-management and operation optimizationThe focus of the project is the formulation of this theory and the development of a suitable tool, as basis to design and evaluate concepts of future energy system. Within the project the theory is translated into a mathematical model, which is the basic for a first exemplary implantation of the LoCA-theory in a software tool. The following simulation starts with small clearly arranged energy systems to test and review the implementation. At the end, bigger and complex energy systems will be simulated to demonstrate the ability of this method. The knowledge gained feed back and refine the theory.The final LoCA theory offers a method to develop and evaluate innovative energy systems and a tool for simulating different configurations.

可再生能源（RES）的使用将在未来大幅增加。实际的电力、燃气和供热系统在过去的100年里不断发展，其目的是将能源从大型中央发电厂传输到分布式消费者。为了通过RES处理大量波动的馈入，它不仅必须被加强，而且必须从根本上进行改造。不断重复的调整只是对脆弱性的渐进修补。为了保证正确的转换，必须设置一个参考目标。新的环-圈-弧理论（LoCA）将细胞设计、分形组织和联合能量载体结合起来，提供了一种设计和评价这一转化目标的方法。细胞设计将能量平衡组理解为自组织和自优化的能量细胞。分形组织描述了整体与其各个部分之间的自相似性。能源载体不再单独考虑和交易，而是相互补充。电、气、热的结合增加了协同效应。在一次又一次使用的局部区域理论中，中心元素是能量单元，从这一点开始称为单元。每个Cell都有一个Port，一个Source，一个Storage，一个Converter和一个Sink。Cell提供了自我管理和操作优化的算法该项目的重点是制定这一理论和开发合适的工具，作为设计和评估未来能源系统概念的基础。在该项目中，该理论被转化为数学模型，这是在软件工具中首次示例性植入LoCA理论的基础。下面的模拟从小的明确安排的能源系统开始，以测试和审查的实施。最后，通过对大型复杂能源系统的仿真，验证了该方法的有效性。所获得的知识反馈并完善了理论。最终的LoCA理论提供了开发和评估创新能源系统的方法，以及模拟不同配置的工具。
