| 摘要: |
| “源-网-储”协调规划是提高非水可再生能源发电量占比的关键技术之一。计及非水可再生能源和负荷的时序特征，提出了基于时序生产模拟的“源-网-储”协调规划方法。在静态规划的基础上，考虑电源、网架和储能的动态运行特征，将非水可再生能源发电量占比作为约束条件以提高模型的适用性。采用多面体集合刻画非水可再生能源和负荷的不确定性，建立满足非水可再生能源发电量占比目标的两阶段鲁棒优化模型，并引入不确定性调节参数以降低决策方案的保守性。通过强对偶理论和大M法将难以直接求解的min-max-min问题转化为双层规划问题，并采用列和约束生成算法求解得到非水可再生能源和储能的多点布局方案以及线路扩展方案。以IEEE 118节点系统为算例，分析了非水可再生能源消纳目标及不确定性对规划方案的影响，结果验证了所提方法的有效性。 |

| Abstract: |
| Coordinated planning of “generation-grid-storage” is one of the key technologies to increase the power generation proportion of non-hydro renewable energy. Considering the sequential characteristics of non-hydro renewable energy and load, a coordinated planning method of “generation-grid-storage” is proposed based on sequential production and simulation. On the basis of static programming, considering the dynamic operation characteristics of power source, grid and energy storage, the proportion of non-hydro renewable energy generation is taken as a constraint condition to improve the model’s applicability. The uncertainties of non-hydro renewable energy and load are described by polyhedron set, a two-stage robust optimization model is established to satisfy the power generation proportion target of non-hydro renewable energy, and uncertainty adjustment parameters are introduced to reduce the conservativeness of decision schemes. The strong dual theory and large-M method are used to transform the min-max-min problem, which is difficult to be solved directly, into a two-level programming problem, and column and constraint generation algorithm is used to obtain the multi-point layout scheme of non-hydro renewable energy and energy storage together with the line expansion scheme. Taking IEEE 118-bus system as an example, the influence of non-hydro renewable energy consumption target and uncertainties on the planning scheme is analyzed, and the effectiveness of the proposed method is verified by the simulative results. |
