摘要
双电层超级电容器兼具蓄电池能量密度大和电解电容器功率密度大的优点,循环寿命长、储能效率高、充放电速度快、高低温性能好、环境友好,具有卓越的储能潜力。本文以光伏系统为例,研究了超级电容器储能以及超级电容器蓄电池混合储能在分布式发电系统中的应用;并探讨了超级电容器对分布式电力系统小信号稳定性的改善作用。
    介绍了太阳能电池及光伏系统的特性,给出了一种基于dP dD的最大功率点跟踪控制策略及其理论依据。介绍了超级电容器工程用等效电路模型,构建了超级电容器储能独立光伏系统,并进行控制环节和能量管理过程设计。仿真及实验表明,超级电容器的充放电效率高达92.5%,所用的MPPT方法具有较好的跟踪速度和精度,系统在光伏发电功率波动和负载功率脉动时,呈现出良好的稳定性。
    建立了超级电容器蓄电池直接并联储能的等效模型,针对脉动负载,分析了储能系统的性能改善及其影响因素。对三种混合储能结构进行了理论分析、仿真和实验。在有源式混合储能结构中,采用了一种蓄电池近似恒流放电控制策略,蓄电池只以脉动负载的平均功率输出,放电过程具有明显的优化效果。
    提出了将超级电容器蓄电池混合储能应用于光伏等分布式发电系统,以优化蓄电池的充放电过程。将光伏阵列及充电控制器等效为脉动电流源,分析了混合储能的响应。提出了一种无源式混合储能方案,可以较好地优化蓄电池的充放电过程。给出了一种有源式混合储能方案,并提出了一种蓄电池优化充电控制策略。对两种储能结构进行了仿真分析和实验验证。
    分析了混合储能的技术经济性。驱动脉动负载时,蓄电池的输出电流峰值远小于负载的脉动电流峰值,可以减少蓄电池组的配置容量,降低安装成本。利用超级电容器的储能能力和并联控制器的变流控制作用,可以减少蓄电池的充放电小循环次数,减小放电深度,延长蓄电池的使用寿命,降低运行成本。
    探讨了直流分布式电力系统的小信号稳定性问题。分析了恒功率负载的负阻性以及各种功率模块之间较强的相互作用对系统稳定性的影响。介绍了稳定性的阻抗分析法,包括稳定禁止区域、阻抗规范,以及稳定裕度的测试等。超级电容器的等效源阻抗很小,本文提出,将超级电容器与系统中的直流母线并联,以降低源输出阻抗,使系统环路增益的奈氏曲线远离禁止区域,从而提高稳定性能或带载能力。并以光伏系统的实例分析证实了可行性。
As a promising energy storage element, Electric Double Layer Capacitor (EDLC) has thevirtues of both high energy density of battery and high power density of electrolytic capacitor.Moreover, it has long cycle life, high storage efficiency, sound temperature adaptability andenvironmental character. EDLC storage system and EDLC/Battery hybrid storage system andtheir application in Distributed Generation (DG) systems were studied in the paper with stand-alone Photovoltaic (PV) system as an example. Small signal stability improvement of
    Distributed Power System (DPS) with EDLC was explored in the paper.The character of solar cell and PV system were introduced. An effective MaximumPower Point Tracking (MPPT) method ( dP dD)and its theoretic basis were presented. Anengineering-oriented simplified equivalent model of EDLC was given and then the equivalentmodel of stand-alone PV system with EDLC as energy storage was set up. The control loopand energy management process were designed. Simulation and experiment results show thatthe charging/discharging cycle efficiency of EDLC is as high as 92.5% and PV array canoperate on the maximum power point quickly and precisely. System is very stable when thegenerating power of PV array or the load power fluctuating.
    The equivalent model of directly paralleled EDLC/Battery hybrid was setup and theperformance and its influence factors were analyzed quantificationally with pulsant load as anexample. Three hybrid structures including passive and actively controlled hybrids wereexplored including theoretic analysis, simulation, experiment, and character comparison. As tothe actively controlled hybrid, a method was presented which can make the discharge currentof battery nearly constant and its output power equal to the average power of the pulsant load.
    The discharge process of battery is optimized markedly.The idea of EDLC/Battery hybrid as the storage of stand-alone PV system was advancedin the paper to optimize the operating process of battery and then lengthen its lifetime. Theperformance of the hybrid was analyzed quantificationally taking PV array and its chargecontroller as pulsant power supply in an uttermost situation. A passive hybrid structure wasbrought forward originally which can optimize the charge/discharge process of battery. Anactively controlled hybrid structure was also given which can make the energy managementflexible through the control of parallel controller. As to the actively controlled structure,battery can be charged with optimized current under a special method advanced in the paper.
    The economic performance of the EDLC/Battery hybrid was analyzed. When drivingpulsant load, the battery capacitance and cost can be reduced greatly since battery just afford
    the average power of the load. The charging and discharging cycles can be reduced thanks tothe long cycle life of EDLC and the power converter between EDLC and battery. As a result,the life of battery is prolonged and then the operating cost is lessened.The small signal stability of DC DPS was explored. Two factors influencing systemstability including the negative impedance of constant power converter and the interactionsamong converters were analyzed. The method for checking small signal stability wasintroduced including forbidden region, impedance specification and stability marginmeasurement. The idea was brought forward that the small signal stability of DC DPS can beimproved with EDLC paralleled connected to the DC BUS. Due to the small equivalentimpedance, the output source impedance is reduced and the Nyquist curve of the system loopgain is far from the forbidden area. It was proved proper in a PV system.
