中文摘要: 新形势下,电力系统中输配交融、交直流混合、电能双向流动,其中柔性控制技术、主动与可再生的被动电源、常规与具有主动行为的负荷等共存,这导致满足有功平衡中应对强不确定性的源网呈现交织纠结的矛盾,而目前仅依赖于主动电源协调调度难以抑制这一矛盾,无法充分实现节能减排。对此,本项目提出电力系统协同调度理论研究:思路是在协调有功平衡过程中,挖掘协同效应,合作地化解不确定性,实现协同调度;核心是在引起矛盾多方间、建立以主动负荷消除强不确定性为目的的合作机制,并将该机制嵌置于三次、二次和一次调整的全程协调中,在主动电源与柔性控制技术协同的电压支撑下,协调与合作有机统一地完成调度目标;重点是主动负荷消除强不确定性的源协同、网络形态同调于源的源网协同、分布自治与全局统筹的源网协同聚类的调度模型、算法与实现;目的是更有效接纳被动电源、遏制化石能源发电。该研究切合电网智能化理念,具有明显理论意义和迫切需求性。

英文摘要: Nowadays, power system is characterized by integrated transmission & distribution system, hybrid AC/DC transmission and bidirectional power flow. Flexible voltage control techniques, active and renewable reactive sources, regular and active loads coexist in the power system. This results in complex contradictions between networks and sources which need to deal with the strong uncertainty during real power balance. Currently these contradictions are difficult to be suppressed only by coordination dispatch of active power sources. Energy-saving and emission-reduction cannot be efficiently realized. In this project, the synergistic dispatch theory of power system is proposed. The idea is to explore the synergy effect, eliminate the uncertainty cooperatively, and realize the synergistic dispatch during the real power balance procedure. The objective is to establish the cooperation mechanism to absorb the strong uncertainty by active loads among contradiction-makers. And the mechanism will be embedded in the primary, secondary, and tertiary dispatch procedures. Finally, the dispatch problem can be solved considering the voltage supported by active power sources and flexible voltage control techniques. The key point of the research is to establish the source synergistic dispatch which can eliminate the strong uncertatinty by active load, source-network synergistic dispatch which considers the interaction between sources and networksand source-network synergistic clustering dispatch which is considered in system level. The algorithms and realization of these dispatch models will also be analyzed. The aim is to increase the penetration level of renewable energy, and decrease the consumption of fossil fuels. The research coincides with the development of smart grids, and has significant theoretical and realistic meanings.
