Abstract To maximize improving the tracking wind power output plan and the service life of energy storage systems (ESS), a control strategy is proposed for ESS to track wind power planning output based on model prediction and two-layer fuzzy control. First, based on model predictive control, a model with deviations of grid-connected power from the planned output and the minimum deviation of the remaining capacity of the ESS from the ideal value is established as the target. Then, when the grid-connected power exceeds the allowable deviation band of tracking, the weight coefficients in the objective function are adjusted by introducing the first layer of fuzzy control rules, combining the state of charge (SOC) of the ESS with the dynamic tracking demand of the planned value of wind power. When the grid-connected power is within the tracking allowable deviation band, the second layer of fuzzy control rules is used to correct the charging and discharging power of the ESS to improve its ability to track the future planned deviation while not crossing the limit. By repeatedly correcting the charging and discharging power of the ESS, its safe operation and the multitasking execution of the wind power plan output tracking target are ensured. Finally, taking actual data from a wind farm as an example, tests on a simulation platform of a combined wind-storage power generation system verify the feasibility and superiority of the proposed control strategy.
摘要为了最大限度地提高储能系统跟踪风电输出计划和使用寿命,提出了一种基于模型预测和双层模糊控制的储能系统跟踪风电规划输出控制策略。首先,基于模型预测控制,建立以并网功率偏离计划输出、ESS剩余容量偏离理想值最小为目标的模型;然后,当并网功率超出跟踪允许偏差范围时,通过引入第一层模糊控制规则,结合ESS的荷电状态(SOC)和风电规划值的动态跟踪需求,对目标函数中的权重系数进行调整;当并网功率在跟踪允许偏差范围内时,采用第二层模糊控制规则对ESS的充放电功率进行校正,提高ESS在不超过限值的情况下跟踪未来计划偏差的能力。通过对ESS充放电功率的反复校正,保证了ESS的安全运行和风电计划输出跟踪目标的多任务执行。最后,以某风电场的实际数据为例,在一个蓄风联合发电系统仿真平台上进行了测试,验证了所提控制策略的可行性和优越性。

Abstract In this paper, a virtual synchronous generator (VSG) controller is applied to a hybrid energy storage system (HESS) containing a battery energy storage system and supercapacitor storage system for maintaining the frequency stability of an isolated microgrid. The microgrid contains a photovoltaic generation system and a diesel generator in addition to the HESS and two constant impedance loads that are fed through a medium voltage radial feeding system. The adaptive virtual inertia constant (H) with constant virtual damping coefficient (D) based on ‘ bang-bang’ control for the microgrid’s frequency stability enhancement is investigated and compared with the constant parameter VSG. In addition, the bang-bang control is modified to adapt the D beside the adaptive H, and the system response is investigated and compared with the conventional adaptive H technique. The VSG parameters are evaluated based on two different methods. The first is a computational method based on the simplified small signal stability analysis, while the other is based on an optimization method using two different objective functions and the particle swarm optimization technique. This paper also investigates the superiority of the proposed technique compared to other techniques in enhancing frequency stability, accelerating steady-state frequency restoration, and reducing the energy requirement of the HESS. The required power from the HESS is shared between the two energy storages using the low pass filter technique so as to reduce battery peak current.
摘要:本文将虚拟同步发电机(VSG)控制器应用于包含电池储能系统和超级电容器储能系统的混合储能系统(HESS)中,以维持孤立微电网的频率稳定性。微电网除HESS外,还包括一个光伏发电系统和一个柴油发电机,以及两个通过中压径向馈电系统馈电的恒阻抗负载。研究了基于“砰砰”控制的自适应虚拟惯性常数H和恒定虚拟阻尼系数D对微电网频率稳定性的增强作用,并与恒参数VSG进行了比较。此外,除了自适应H外,还对砰砰控制进行了修改以适应D,并对系统的响应进行了研究,并与传统的自适应H技术进行了比较。基于两种不同的方法对VSG参数进行了评估。一种是基于简化小信号稳定性分析的计算方法,另一种是基于两种不同目标函数和粒子群优化技术的优化方法。与其他技术相比,本文还研究了该技术在提高频率稳定性、加速稳态频率恢复和降低HESS能量需求方面的优越性。HESS所需的功率通过低通滤波技术在两个储能系统之间共享,从而降低电池峰值电流。

Abstract Accurate evaluation of power losses in a modular multilevel converter (MMC) is very important for circuit component selection, cooling system design, and reliability analysis of power transmission systems. However, the existing converter valve loss calculation methods using the nearest level modulation (NLM) method and the traditional sorting-based capacitor voltage balancing strategy are inaccurate since the submodule (SM) switching logics in the MMC arms are uncertain. To solve this problem, the switching principle of the SMs in the sorting-based voltage balancing strategy is analyzed. An accurate MMC power loss calculation method based on the analysis of loss distribution of various SM topologies, including half-bridge submodule (HBSM), full-bridge submodule (FBSM) and clamp double submodule (CDSM), is proposed in this paper. The method can accurately calculate the losses caused by the extra switching actions during the capacitor voltage balancing process, thus greatly increasing the calculation accuracy of switching losses compared with existing methods. Simulation results based on a practical ± 350 kV/1000 MW MMC-HVDC system with variety of MMC topologies with different voltage balancing strategies demonstrate the effectiveness of the proposed method.
摘要准确评估模块化多电平变换器(MMC)的功率损耗对电路元件选择、冷却系统设计和输电系统可靠性分析具有重要意义。然而,由于MMC臂中的子模块(SM)切换逻辑不确定,现有的基于最近电平调制(NLM)方法和传统的基于分选的电容器电压平衡策略的换流阀损耗计算方法不准确。为了解决这一问题,分析了基于分选的电压平衡策略中SMs的开关原理。本文在分析半桥子模块(HBSM)、全桥子模块(FBSM)和箝位双子模块(CDSM)等各种SM拓扑损耗分布的基础上,提出了一种精确的MMC功率损耗计算方法。该方法可以准确地计算出电容器电压平衡过程中额外开关动作所造成的损耗,与现有方法相比,大大提高了开关损耗的计算精度。基于±350kv / 1000mw MMC- hvdc实际系统的仿真结果验证了该方法的有效性,该系统具有多种MMC拓扑和不同的电压平衡策略。

Abstract Owing to their flexibility and rapid response, grid-connected distributed energy resources (DERs) are wielding growing influence in frequency regulation markets (FRMs). Nevertheless, compared with conventional large-scale generators, small-scale DERs are usually weakly shielded by cyber security measures. This offers attackers the opportunity of disrupting the clearing and settlement of FRMs by manipulating the bid information of DERs. In this paper, the frequency regulation market equilibrium is studied considering the dynamic gaming between attackers and defenders, both of which need the knowledge of FRMs for their interventions. Specifically, a tri-level programming model characterizing the attacker–defender–operator (ADO) interdiction problem in FRMs is developed and then analyzed using a column and constraint generation algorithm, thereby achieving market equilibrium representing the defender's best response to the attacker. The defense strategy in the market equilibrium can attenuate the negative influence of cyber attacks upon the FRMs to the maximum extent. Finally, based on the operating rules of the California Independent System Operator, the FRM process considering the ADO interdiction is simulated and the numerical equilibrium results are presented.
摘要并网分布式能源以其灵活性和快速响应能力,在频率调节市场中发挥着越来越大的作用。然而,与传统的大型发电机相比,小型der通常受到网络安全措施的保护较弱。这为攻击者提供了通过操纵DERs的出价信息来破坏frm清算和结算的机会。本文考虑攻击者和防御者之间的动态博弈,研究频率调节市场均衡,攻击者和防御者都需要frm的知识进行干预。具体地说,建立了表征FRMs中攻击者-防御者-操作员(ADO)拦截问题的三层规划模型,并使用列约束生成算法对其进行了分析,从而实现了代表防御者对攻击者的最佳响应的市场均衡。市场均衡下的防御策略可以最大程度地减弱网络攻击对企业的负面影响。最后,基于加州独立系统算子的操作规则,对考虑ADO拦截的FRM过程进行了仿真,并给出了数值平衡结果。
