基于随机的配电系统微网日能量优化管理

Stochastic-based Optimal Daily Energy Management of Microgrids in Distribution Systems

Farhad Samadi Gazijahani, Javad Salehi

摘要:

微电网采用不同的分布式发电技术和不同的控制设施,需要适当的管理和调度策略。在这些策略中,为了达到最优管理,必须考虑某些决策变量的随机性。因此,我们提出了一种新的基于随机的方法,最佳的每日能源管理(SDEM)的MG考虑经济性和可靠性方面。优化目标是使总运行成本、网损成本、污染物排放成本和非供能成本最小。该网络被假定由可再生和可调度发电机和储能系统(ESS)供电。系统的不确定性被认为是使用一组场景和场景减少方法,以提高解决方案的准确性和计算负担之间的权衡。采用布谷鸟优化算法(COA)来最小化目标函数作为优化算法。通过对PG&E 69节点试验配电系统的大量数值试验,验证了所提方法的有效性和高效性。结果表明,所提出的框架可以被认为是一个有效的工具,在智能配电网的日常能源管理优化。

英文摘要:

Microgrid (MG) with different technologies in distributed generations (DG) and different control facilities require proper management and scheduling strategies. In these strategies, in order to reach the optimal management, the stochastic nature of some decision variables should be considered. Therefore, we proposes a new stochastic-based method for optimal daily energy management (SDEM) of MGs considering economic and reliability aspects. The optimization aim is to minimize overall operating cost, power losses cost, pollutants emission cost and cost of energy not supply (ENS). The network is assumed to be supplied by renewable and dispatch able generators and energy storage systems (ESS). The system uncertainties are considered using a set of scenarios and a scenario reduction method is applied to enhance a trade-off between the accuracy of the solution and the computational burden. Cuckoo optimization algorithm (COA) is applied to minimize the objective function as an optimization algorithm. The effectiveness and efficiency of the proposed method are validated through extensive numerical tests on PG&E 69-bus test distribution system. The results show that the proposed framework can be considered as an efficient tool in optimal daily energy management of smart distribution networks.
