| 摘要: |
| 分析了分散式能源及其发电的特点,指出与常规能源发电的最大差异是不可控的随机特性。当大规模的随机发电能力接入电力系统以后,产生了随机的发电与随机的用电两组不相关的变量要求其实时平衡的科学问题。需要在电源规划、电网规划、运行控制和故障保护等多方面考虑可控的常规发电与随机的发电合理组合后满足随机变化的负荷需求,形成了一系列新的技术问题,从分散式电源接入电力系统的优化规划及可靠性评估、运行分析及控制调节策略、相关继电保护及安全自动装置等方面指出了应当开展的研究。 |

| Abstract: |
| The features of distributed energy and its generation are analyzed and it is pointed out that the main difference between distributed generation and traditional energy generation is the uncontrollable stochastic characteristic.When large-scale distributed generation is connected to power system,the real-time balance of two irrelevant variables,i.e.stochastic generation and stochastic load,is a scientific issue.To find a rational combination of controllable traditional generation and uncontrollable stochastic generation meeting the stochastic load demands,considera-tions in many aspects are necessary,such as generator planning,power grid planning,operational control,fault protection,and so on,which brings about new technical problems.It is suggested to expand the research in the optimal planning and reliability assessment,the operational analysis and control strategy,the protection and safety equipment,and so on. |
