摘要

构建以新能源为主体的新型电力系统，亟须挖掘负荷侧灵活调节资源参与电网调控。含电解铝、矿热炉等高耗能负荷的工业园区具备良好的调控潜力，但是考虑园区内部电力网络约束，其精确调控边界求解面临着变量维数高、约束非线性的难题，现有方法不能较好地兼顾计算效率和精度。对此，文中将上述问题抽象为高维非线性状态空间在

P-Q

耦合平面的投影问题：分别建立考虑工业园区安全运行线性化和非线性约束的调控边界投影求解模型，采用一种新颖的高维状态空间投影算法，通过顶点“搜索-映射”的两步式求解过程，得到工业园区型虚拟电厂调控边界的精确投影。算例结果表明，采用所提方法求解的调控边界可由线性不等式组完全表征，与现有调度系统完全兼容，结合与叠加柔性资源调控能力和传统采样方法的对比，验证了该方法的可行性以及高求解精度和效率。

Abstract

To construct a new power system with renewable energy as its primary component

it is urgent to explore the flexible regulation resources on the load side to participate in grid control and regulation. Industrial parks that contain high energy-consuming loads

such as aluminium electrolyzers and mineral heat furnaces

have good potential for control and regulation. However

due to the constraints of the internal power networks of the parks

accurately solving the regulation boundary is faced with the difficulties of high dimensionality of the variables and non-linearity of the constraints

and the existing methods don’t take into account the computational efficiency and accuracy very

well. Hence

the above problem is abstracted as the projection of high-dimensional nonlinear state space in the

coupling plane: the projection solution models of the regulation boundary considering the linearized and nonlinear constraints on the safe operation of the industrial park are established

respectively

and a novel high-dimensional state space projection algorithm is adopted to obtain the accurate projection of the regulation boundary of the industrial park virtual power plant through the two-step solution process of vertex “searching-mapping”. The results demonstrate that the regulation boundary solved by the proposed method can be fully characterised by a linear inequality set

which is fully compatible with the existing scheduling system. Combined with the comparison with the superimposed flexible resource regulation capability and the traditional sampling method

the feasibility

and high accuracy and solution efficiency of the method are verified.
