摘要:
为了提高区域多微电网群的运行效率以及节省运行成本,依托图论和缺电调度合约,建立需求侧相互支援的多微电网虚拟备用模型,同时将不确定性变量融入激励性需求响应模型中。结合IEEE 33节点系统内区域多微电网模型,讨论缺电调度中虚拟备用和需求响应成本与合约购电比例的关系,证明了缺电调度合约的吸引力。对日内不同随机缺电情景进行仿真和成本对比,结果证明了所提模型在缺电调度中具有成本优势。

Abstract:
In order to improve the operation efficiency and save the operation cost of multi-microgrid clusters, on the basis of graph theory and power shortage dispatching contract, a virtual reserve model of multi-microgrid with mutual support at demand side is built, meanwhile the uncertainty variables are integrated into incentive-based demand response model. Combined with the regional multi-microgrid model in IEEE 33-bus system, the relationship between virtual reserve and demand response costs and contract power purchase proportion in power shortage dispatching is discussed, which verifies the attraction of power shortage dispatching contract. The simulation and cost comparison of different random power shortage scenarios within a day are carried out, and results verify that the proposed model has cost advantage in power shortage dispatching.
Key words:  multi-microgrid clusters  power shortage dispatching contract  virtual reserve  uncertainty  demand response  resource allocation
