Research on Technical Management of Distributed Generators based on Decentralized Supply Responsibility

该研究项目旨在研究一种新的框架，将供电责任分散到控制每个社区内分布式发电机的本地独立系统操作员之间。主要结果如下：1.通过在配电网和用户之间引入能量管理中心(EMC)安装的储能系统和功率转换装置，使分布式发电机的功率输出平滑，并在孤岛区域内维持规定的电压和持续供电。研究了EMCS和客户通过通信网络直接或间接控制参与系统运行的技术管理问题。结果表明，EMC引入实时电价可以降低系统操作员对负荷频率控制的责任，提高负荷率。仿真了分布式电源对供电和备用的贡献方法，并给出了E-…更多的是量化评估。结果表明，系统操作员为电能供应和控制准备的装机容量可能会减少。研究还表明，根据客户需求调节可靠性比统一调节更为经济。提出了地区配电网可靠性、系统故障电能质量、降低成本的评估方法，为引进分布式发电机和储能系统提供咨询服务的可能性。建立了基于基本交易规则的电力市场仿真模型，该模型考虑了区域与系统运营商之间的电力交换。针对放松管制下保障运营储备这一重要问题，提出了两种基本解决方案，并对其进行了评价。配电网可靠性评估分两种情况进行，即每个EMC直接负责供电和由区域内的EMC负责的地方独立系统操作员负责。结果表明，前者有利于降低社会成本。较少

This research project aimed to investigate a new framework for decentralizing supply responsibility among local independent system operators which control distributed generators within each community areas.The brief results are as follows :1. By introducing Energy Management Center (EMC) installed energy storage systems and power conversion devices between distribution network and customers, smoothing power outputs of distributed generators, maintaining specified voltages and continuing power supply within islanded area are enabled.2. Technical management of EMCs and customers to participate them in system operation by direct or indirect control using communication network was investigated. As a result, it was conformed that the liability of system operator for load frequency control could be reduced and load factor would be improved by EMC introducing real-time pricing of electric energy.3. Contribution method of distributed generators for power supply and reserves was simulated and e … More valuated quantitatively. As a result, it was revealed that the installed capacity prepared by system operator for electric energy supply and control could be reduced. It was also revealed that regulating reliability depended on customer's needs was more economical than regulating uniformly.4. Possibility of consulting service about introduction of distributed generators and energy storage systems was presented by developing evaluation method for local distribution system's reliability, power quality against system faults and cost reduction.5. Market simulation model based on essential trading rules was developed considering power exchange between local areas and system operator. Two basic solutions for the important issue to secure operation reserves under deregulation were developed and evaluated.6. Assessment of distribution network reliability was carried out in two cases that each EMC took responsibility for power supply directly and local independent system operator which supervised EMCs in the area took it. It was conformed that the former is favorable for social cost. Less
