New paradigms in operations and planning of power distribution systems in the deregulated environment

随着分布式发电(DG)电源技术的发展和电力行业零售竞争的到来，配电公司(DISCO)的作用逐渐演变为整个电力系统健康高效运行的关键。迪斯科舞厅除了对服务质量和可靠性作出贡献外，还影响了市场运作，改善了竞争和运作的技术方面。在同样的背景下，需求响应计划/需求侧管理(DSM)是重要的政策工具，能够改变配电系统内的潮流模式，并为提高整个系统的经济效率和安全运行做出重大贡献。

As a result of recent technological developments in distributed generation (DG) sources and with the advent of retail competition in the electric power industry, the role of the distribution companies (discos) has gradually evolved into a very important and critical one for a sound and efficient operation of the whole power system. The discos have affected market operations and improved competition and technical aspects of operation in addition to their contribution to service quality and reliability. In the same context, demand response programs/demand side management (DSM) are important policy tools that have an ability to alter power flow patterns within the distribution systems and contribute significantly to enhance the economic efficiency and secure operation for the whole system.
