摘要

由于新能源出力的随机不确定性及源荷分布的不平衡，区域电力系统的调峰压力日益加大，利用燃气机组深度变负荷能力进行调峰是解决该问题的一个思路。分析了中国现有燃气机组的调峰能力，针对燃气机组深度变负荷调峰与启停调峰这两种深度调峰方式，研究了燃气机组深度变负荷调峰过程中的附加成本，提出了其参与系统调峰控制的全过程调峰成本。在全额接纳风电的基础上，以系统发电成本最小为目标，建立了考虑燃气机组附加成本的电力系统经济调度模型。进而从经济、社会、环境角度建立电力系统能源效率指标，评估燃气机组参与深度调峰的经济性与可行性。以某实际电网为实例进行仿真验证，结果表明综合考虑系统能源优化与环境因素，在非采暖期采用燃气机组深度调峰具有合理性；同时需要建立考虑燃气机组附加成本的经济调度机制，以提高电力系统的整体能源效率。

Abstract

Due to the random uncertainty of the new energy and the imbalance of the source and load distribution

the peak regulation pressure of regional power system is increasing recently. To solve the problem

one feasible way is to utilize the deep peaking ability of gas unit for peak regulation. Peak regulation capacity of the existing gas unit is analyzed. For the two regulation modes of gas unit deep variable load peak and start-stop peak

the additional cost in the process of gas unit deep peak regulation is studied and the gas unit's whole process peaking cost is proposed. To minimize the generation cost of the system

the economic dispatching model of the power system in consideration of gas unit's additional cost is established based on the full acceptance of wind power. The economy and feasibility of gas unit participating in deep peak regulation is assessed by the energy efficiency indexes established from the economic

social and environmental perspective. Simulation results for an actual system show that

in the non-heating period

the gas unit should operate in the deep peak regulation state when the system energy optimization and environmental factors are considered. The economic dispatching mechanism should be constructed when considering the additional cost of the gas unit to improve the overall energy efficiency of the power system.
