13. LFC with MPC

  利用 MPC算法使得由发电机参数摄动和负荷扰动形成的电网频率波动减小。为验证所提出方案的有效性,建立三区域互联电力系统频率响应模型并仿真,将 MPC算法与常规的PID算法控制效果进行比较。结果表明,在负荷扰动、参数摄动和有通信延迟的情况下,MPC技术对互联电网的负荷频率控制性能均优于PID控制(The MPC algorithm is used to reduce grid frequency fluctuations caused by generator parameter perturbations and load disturbances. In order to verify the effectiveness of the proposed scheme, a three-zone interconnected power system frequency response model is established and simulated, and the MPC algorithm is compared with the conventional PID algorithm. The results show that under load disturbance, parameter perturbation and communication delay, MPC technology is better than PID control for the load frequency control performance of the interconnected power grid.)

15. CCHP

  针对冷热电联供型微网中的负荷类型建立能量平衡约束条件。冷热电联供型多微网和主动配电网作为两个不同的利益主体,采用分布式建模方法,建立不同的经济优化目标,联络线电功率作为两者的耦合变量,等效为虚拟负荷和虚拟电源实现冷热电联供型多微网主动配电系统优化模型的并行求解。天津中新生态城的算例表明冷热电联供 型多微网主动配电系统优化经济调度是有效的,能够实现两个利益主体的经济最优。(The energy balance constraint conditions are established for the load types of CCHP. As two different stakeholders, the cold, heat and power co-generation multi-micro-grid and the active distribution network adopt the distributed modeling method to establish different economic optimization objectives. The tie-line power is the coupling variable of the two and is equivalent to the virtual load and the virtual power to realize the optimization model of the cold, heat and power co-generation multi-micro-grid active distribution system. Parallel solution. The example of Tianjin new China eco city shows the combined cooling heating and power system.)

  文章以含有蓄电池、光伏、风机以及负荷的微电网为研究对象,在考虑蓄电池充放电约束、微电网与电网功率交换约束等条件下,建立了以负荷平均供电单价最小为目标的日前优化调度模型。并利用改进交叉算子的遗传算法进行求解。以某典型微电网为例进行建模与求解,得到了微电网日前优化调度方案,实现了微电网的经济稳定运行(Taking the micro-grid with storage battery, photovoltaic, fan and load as the research object, considering the battery charging and discharging constraints, power exchange constraints between micro-grid and power grid, a daily optimal dispatching model with the objective of minimizing the average unit price of power supply is established. The improved crossover operator is used to solve the genetic algorithm. Taking a typical micro-grid as an example, the day-ahead optimal dispatching scheme of micro-grid is obtained, and the economic and stable operation of micro-grid is realized.)

19. SMES_BESS 储能变流器

  储能系统在微电网的运行控制中起到了重要的作用, 研究了超导磁储能和蓄电池储能系统的储能变流器在微电 网中的控制策略。基于比例积分(proportional-integral,PI) 控制的储能变流器已广泛应用于微电网中,以实现双向的功 率传输。然而,由于储能变流器具有高度的非线性和耦合性, PI 控制器无法实现令人满意的鲁棒性。因此提出了一种基 于互联和阻尼配置方法的能量成型控制策略,用于改善微电 网中混合储能系统储能变流器的鲁棒性。(Energy storage system plays an important role in operation and control of microgrid. Control strategies of converters of superconducting magnetic energy storage (SMES) system/battery hybrid energy storage system (HESS) in microgrid are studied in this paper. Energy storage converters are widely used in microgrid for achieving bidirectional power transmission based on proportional-integral (PI) method. However, PI controllers are not satisfactory in robustness due to high nonlinearity and coupling characteristics. Thus, this paper proposes an energy shaping (ES) control based on interconnection and damping assignment (IDA) to improve robustness of HESS converters in microgrid. Design process includes three steps: construction of port-controlled Hamiltonian (PCH) model, setting of desirable equilibrium and solution of energy matching equation.)
