风力发电和光伏发电并网问题研究

摘要

风力发电和光伏发电是一类特殊的电力,具有许多不同于常规能
源发电的特点,由于其并入电网的电能呈波动性,大规模的风电和光
电并网对电网的安全稳定、运行调度等诸多方面都会有一定影响。
本文设计了含风力发电和光伏发电的电力系统发电容量模型和
算法,进行了基于蒙特卡罗仿真的风力发电的发电容量可信度评估,
计算了接入风力发电机组和光伏发电机组后电网的可靠性指标和节
约的燃煤量,同时分析了不同时间段和不同气象条件对可靠性指标
LOLE 的影响,而后探讨了接入储能装置对于可靠性指标产生的影响。
本文设计了计算准入功率的优化算法,并运用试探法计算了风力发电
和光伏发电的最大准入功率。本文还讨论了风力发电和光伏发电机组
在不同位置接入配电网对电压水平的影响,重点研究了当风力发电和
光伏发电机组位于馈线上时,其对电压水平的影响。
在节能环保方面,本文为风力发电和光伏发电并网进行了节能环
保价值分析,给出了风电价值的详细表达式,探讨了光伏发电的能量
回收情况,设计了环境成本的计算方法。此外,本文建立了考虑环境
成本、阻塞成本、煤耗以及网络约束的风火电厂间的发电权交易模型,
并设计了详细的发电权交易流程。

RESEARCHES ON WIND POWER AND
PHOTOVOLTAIC GENERATION INTEGRATION INTO
POWER SYSTEM

ABSTRACT

Wind power and Photovoltaic (PV) generation are different from
conventional power generation for its fluctuating nature. With the
increasing ration level, wind power and PV generation will
influence the stability and dispatching of power system more and more.
Based on Monte Carlo method, this paper creates a generation
capacity model including wind power and PV generation, and presents a
detailed adequacy evaluation scheme to quantitatively evaluate the
capacity-replacement contribution of wind power and PV generation. An
approach which samples the random states of wind power and PV
generation to calculate the reliability indices of the generation system and
the fuel savings is also presented. The values of LOLE in different
periods and under different weather, and the reliability index change
when install the electric energy storage system are analyzed. We
investigate the voltage stability when wind power and PV generation are
integrated in different positions, especially when they are between
transformer and the end of feeder.
In the aspect of energy-saving and emission-reducing, the value of
wind power and PV gen
