【摘要】：电力高峰负荷持续增长及间歇式能源的迅猛发展提高了输电阻塞的风险,对电力系统调度调节能力提出新的重大挑战。传统电网中主要通过动态增容、负荷转供及有序用电来解决网络阻塞问题。智能电网环境下,随着"源—网—荷"互动能力的提升,柔性负荷参与电网调度在解决网络阻塞问题方面发挥着十分经济高效的作用。基于柔性负荷参与地区电网需求响应调度,以"源—网—荷"三方综合效益最大为目标,构建了计及网络约束的发用电一体化综合调度模型,通过形成最优电价和激励调度方案,实现了对发用电侧的协同一体化综合调度,在有效缓解网络阻塞问题的基础上,实现了满意度和互动成本的最优。采用IEEE 14节点算例验证了优化调度模型的经济性和有效性。
[Abstract]:The continuous growth of power peak load and the rapid development of intermittent energy increase the risk of transmission congestion and pose a new major challenge to the power system dispatching and regulating ability. The problem of network congestion is mainly solved by dynamic capacity increase, load transfer and orderly use of electricity in traditional power network. In the environment of smart grid, with the improvement of "source-network-load" interaction ability, flexible load dispatching plays a very economical and efficient role in solving the network congestion problem. Based on the flexible load participating in the demand response dispatching of the regional power network, a comprehensive dispatching model of power generation and power generation and power supply is constructed, which takes the "source-network-load" three-party comprehensive benefit as the goal, and takes the network constraints into account. Through the formation of the optimal electricity price and incentive scheduling scheme, the cooperative integrated integrated scheduling on the generating and power side is realized. On the basis of effectively alleviating the network congestion problem, the satisfaction degree and the interaction cost are optimized. The economy and effectiveness of the optimal scheduling model are verified by a IEEE 14 node example.
