风电功率的随机性对电力系统安全稳定运行提出挑战,同时,系统网架条件、电源结构和负荷特性制约着风电的接入与消纳。为此,建立了风电布局优化模型,以系统风电装机容量最大化为目标,计及网架传输容量限制,采用典型负荷水平反映系统的负荷需求,并考虑常规机组应对风电功率波动的能力。模型应用鲁棒线性优化理论考虑风电随机性,采用盒式集合描述风电功率偏离均值的程度,引入可调节的鲁棒性参数,实现不确定性优化模型向确定性优化模型的转化,进而对风机布点及相应的装机容量进行优化决策。最后,以修正的Graver 6算例系统为例,验证了模型的有效性与合理性。

英文摘要：

The randomness of wind power output makes a challenge to secure and stable operation of power grid, meanwhile, the grid-connection and the accommodation of wind power are restricted by topology of transmission network, capacity proportion of power sources and load characteristics. For this reason an optimization model of wind power capacity allocation is established where the maximal installed capacity of wind power units is taken as the objective and the constraints of transmission capacity of power grid is taken into account and typical load scenarios are utilized to reflect the load demand in power grid and the capability of conventional power units to cope with the fluctuation of wind power output is considered. In the established model, the robust linear optimization theory is represented to consider the randomness of wind power output, and the box set is used to describe the deviation extent of the wind power output from its average value, the adjustable robust parameters are led in to control the robustness of the solution. Through the transition from original problem with stochastic variables to deterministic form, the optimized results of allocated locations for wind farms and the corresponding installed capacities are obtained. Finally, taking the modified Graver 6 system as example, the feasibility and the validity of the proposed model are confirmed.
