摘要:

随着分布式能源的高比例渗透、大量储能单元以及柔性负荷的加入,主动配电网的优化调度变得更加具有挑战性。现有经济调度较少考虑柔性负荷和储能单元的接入,收敛速度较慢。结合国家“双碳”目标,提出FISCO BCOS平台下结合通信拓扑优化一致性算法的配电网多目标经济调度策略。该策略综合考虑发电机发电成本、污染气体排放、储能成本和柔性负荷用电效益,利用通信拓扑优化的一致性算法提高系统收敛速度,结合FISCO BCOS联盟链的存储和精简实用拜占庭容错(rPBFT)共识机制优化节点间的信息共享,降低领导节点的中心性,防止部分节点作恶,实现配电网多目标最优功率分配。仿真结果表明,提出的配电网多目标调度经济调度策略收敛速度快,在领导节点切换、不同阶段节点退出与加入及功率交换指令变化、收敛系数变动场景下仍能较快收敛,具有良好的鲁棒性和稳定性,且收敛速度优于快速一致性算法,若目标权重系数选取恰当,经济与环境结果均优于多目标NSGA-Ⅱ算法。

Abstract:

The high penetration of distributed energy, addition of many energy storage units, and flexible loads have hindered the optimization and scheduling of active distribution networks. Existing economic dispatch systems do not consider the integration of flexible loads and energy storage units effectively, resulting in slow convergence speed. Aligning with the national ″dual carbon″ goals, this paper proposes a multi-objective economic dispatch strategy for distribution networks based on the FISCO BCOS platform, combined with the consistency algorithm in communication topology optimization. This strategy comprehensively considers power generation cost, gas emissions, energy storage cost, and the benefits of flexible load electricity consumption. It uses the consistency algorithm in communication topology optimization to improve the system′s convergence speed. Moreover, it combines the storage of the FISCO BCOS alliance chain and the reduced Practical Byzantine Fault Tolerance (rPBFT) consensus mechanism to optimize information sharing between nodes, reduce the centrality of leading nodes, prevent malicious nodes from attacking, and achieve multi-objective optimal power allocation in the distribution network. Simulation results show that the proposed multi-objective scheduling economic dispatch strategy converges quickly despite leader node switching, node exit and addition at different stages, power exchange instruction changes, and convergence coefficient changes. It is robust, stable, and achieves a higher convergence speed than that of the fast-consistency algorithm. It selects appropriate target weight coefficients, yielding economic and environmental outcomes that are better than those provided by the multi-objective NSGA-Ⅱ algorithm.
