摘要
在发生重大停电事件时,如果移动应急发电机(MEG)能够共享能源,关键园区微电网(PMGs)就能自我维持。然而,隐私保护的需求和分钟级灵活电力支持的价值尚未得到足够重视。为解决这一问题,本文提出了一种新的关键永磁发电机整合移动应急发电机的自我维持策略。首先,为促进 PMG 与 MEG 之间的合作,本文设计了一种双层利益分配机制,即对参与者的多重角色和贡献进行识别,并对良好行为进行奖励。此外,考虑到可再生能源发电和负荷的波动性,为提高联盟效益,提出了三种损耗协调模式,以指导 MEG 和 PMG 在分钟级的电力交换。在此基础上,通过乘法交替方向法(ADMM)制定了多时间尺度的电力-能源调度策略,以协调 PMG 和 MEG。最后,设计了一种降维技术来等效简化优化问题,以促进基于自适应步长的 ADMM 求解。仿真研究表明,所提出的策略实现了永磁发电机与多元气体发电机的自我维持,同时提高了不少于 3.1% 的经济效益。
Self-Sustaining of Critical Park Microgrids Integrating Mobile Emergency Generators Subjective to Major Outage
In the event of a major power outage, critical park microgrids (PMGs) could be self-sustaining if mobile emergency generators (MEGs) are stationed to share energy. However, the need for privacy protection and the value of flexible power support on minute-time scales have not been given enough attention. To address the problem, this paper proposes a new self-sustaining strategy for critical PMGs integrating MEGs. First, to promote the cooperation between PMG and MEG, a bi-level benefit distribution mechanism is designed, where the participants' multiple roles and contributions are identified, and good behaviors are also awarded. Additionally, to increase the alliance benefits, three loss coordination modes are presented to guide the power exchange at the minute level between the MEG and PMG, considering the volatility of renewable generation and load. On this basis, a multi-time scale power-energy scheduling strategy is formulated via the alternating direction method of multipliers (ADMM) to coordinate the PMG and MEG. Finally, a dimensionality reduction technology is designed to equivalently simplify the optimization problem to facilitate the adaptive-step-based ADMM solution. Simulation studies indicate that the proposed strategy achieves the self-sustaining of PMGs integrating MEGs while increasing the economy by no less than 3.1%.
