A comprehensive technical-economic optimization model for electric distribution grids

由于德国的“能源转型”，电力工业，特别是配电网正面临着巨大的技术和监管变革。为了应对这些变化并适应即将到来的需求，配电网运营商必须不断调整其管理策略。现有的配电网子模型主要关注整个业务的孤立方面，如配电网的可靠性或资产管理或资产服务的优化配置。因此，它们只能确定网格业务中单个部件的局部优化策略。这些子模型之间的各种交互和依赖关系或多或少地被忽略了。因此，项目的主要目标是建立一个综合的技术经济优化模型，该模型涵盖了配电网业务的所有相关子模型和方面（可靠性、资产管理、资产服务和监管）。为了结合所有这些方面，开发了一个模块化模型工具包，以分析和了解更多关于子模型之间的定性和定量依赖、相互作用和长期影响的信息。整体配电网优化模型允许对当前和未来的电网任务和结构、资产服务和资产管理组织以及监管和政治框架进行全面模拟，因此能够为配电网运营商的业务定义一个全局的、整体的优化战略。这种最佳策略最终将减少电网供电量，这将对整个经济产生积极的长期影响。德国最大的电网运营公司（Westnetz GmbH）将为该项目提供所需的所有数据，以确保最终的综合优化模型与（实际）实践相一致。

Due to the German "Energiewende" the electricity industry and especially distribution grids are facing tremendous technical and regulatory changes. In order to manage these changes and to match the upcoming requirements distribution grid operators have to adjust their management strategy continuously. Existing submodels for distribution grids mainly focus on isolated aspects of the whole business such as the reliability of distribution grids or an optimized configuration of Asset-Management or Asset-Service. Therefore they can only determine local optimized strategies for single parts in the grid business. The various interactions and dependencies between these submodels are more or less neglected. Therefore, the main project objective is to develop a comprehensive technical-economic optimization model which covers all relevant submodels and aspects (Reliability, Asset-Management, Asset-Service and Regulation) of the electrical distribution grid business. To combine all these aspects a modular model kit is developed in order to analyse and learn more about the qualitative and quantitative dependencies, interactions and long-term effects between the submodels. The overall distribution grid optimization model allows a comprehensive simulation of current and future grid tasks and structures, Asset-Service an Asset-Management organisations as well as regulatory and political frameworks and therefore is able to define a global, overall optimum strategy for distribution grid operators business.This optimal strategy will finally result in reduced grid feeds which will have a positive, long-term impact on the whole economy. Germany's largest grid operating company (Westnetz GmbH) will support the project with all data needed in order to make sure that the final comprehensive optimization model is in step with (actual) practice.
