摘要
针对传统集中式经济调度策略需要获取全局信息以及无法适应系统灵活拓扑的缺陷,同时考虑能量以电能和热量形式并存出现的情况,基于一致性算法提出了一种完全分布式热电联产经济调度策略.将热电联产系统中各机组电价和热价的增量成本作为一致性变量进行迭代计算,直至增量成本达到收敛,实现系统经济最优.此外,还分析了个别机组为了提升自身利益,向相邻机组传输带有偏差增量成本值的情况,设计了一个增量成本补偿项来消除该自私行为的影响.在3个仿真算例中得到的结果表明,所提策略在解决热电联产系统经济调度问题中具有有效性和可行性.
Abstract
In response to the defects of the traditional centralized economic dispatching strategy which needs to obtain global information and cannot adapt to the flexible topology of the system,and considering the coexistence of energy in the form of electricity and heat,a completely distributed cogeneration economic dispatching strategy based on the consistency algorithm is proposed.The incremental cost of electricity price and heat price of each unit in the cogeneration system is taken as the consistent variable to conduct the iterative calculation until the incremental cost converges to achieve the economic optimum of the system.In addition,the case of individual unit transmitting to neighboring units with deviating incremental cost values in order to enhance their own interests is also analyzed,and an incremental cost compensation term is designed to eliminate the impact of this selfish behavior.The simulation results indicate that the proposed strategy is effective and viable in the solution of the cogeneration economic dispatching problems.
