| 摘要: |
| 传统经济性规划方法无法反映电力系统灵活性，难以满足高比例可再生能源电力系统的规划需求，为此，提出一种考虑灵活性与经济性的多目标源网联合规划方法。分析源荷两侧的灵活性需求，并从功率平衡与功率传输两方面实现电源灵活性与电网灵活性的定量评估。在此基础上，综合考虑电源、线路2种灵活性资源，建立兼顾灵活性和经济性的电力系统双层联合规划模型：上层是规划方案的多目标优化决策，实现源网灵活性和经济性的协同优化；下层是多场景运行模拟，对规划方案的灵活性与经济性进行定量评价。IEEE RTS-24节点系统与IEEE 118节点系统的算例结果表明，所提规划方法能够有效响应并平复可再生能源电源与负荷的不确定性功率波动，提高系统的灵活性以及对可再生能源的消纳能力。 |

| Abstract: |
| The traditional economic planning method cannot reflect the system flexibility, so it is difficult to meet the planning demand of high proportion renewable energy power system, for which, a multi-objective source-grid joint planning method considering the flexibility and economy is proposed. The flexibility demands of both the source and load sides are analyzed, and quantitative evaluation of power source flexibility and power grid flexibility are realized from two aspects of power balance and power transmission. On this basis, comprehensively considering two flexibility resources of power source and line, a bi-layer joint planning model considering the flexibility and economy is established. The upper layer is multi-objective optimization decision making of planning scheme, which realizes coordinated optimization of source-grid flexibility and economy, the lower layer is multi-scenario operation simulation, which quantitatively evaluates the flexibility and economy of planning schemes. The case results of IEEE RTS 24-bus system and IEEE 118-bus system verify that the proposed planning method can effectively respond and smooth the uncertain power fluctuation of renewable energy power source and load, and improve the system flexibility and consumption capacity of renewable energy. |
