基于滚动式ADMM算法微电网群调度研究

Research on Microgrid Cluster Scheduling Based on Rolling ADMM

随着可再生能源技术的不断发展,微电网作为分布式电源接入电网的一种有效手段,逐步引起了广泛的关注。但由于单个微电网存在分布式电源接入容量限制、抗扰动能力差等缺陷,降低了负荷的用电稳定性。从而引入了微电网群的概念,微电网群通过多个微电网的协调工作,有效地克服了单个微电网的缺陷,因此对微电网群各个方面进行优化调度也变得越发重要。首先对当天的光能和负载进行预测,然后基于交替方向乘子算法(ADMM)对价格进行最优化,使微电网群的运行成本降到最低,且微电网能够保证关键负载的可靠性和电力质量,提高整个系统的优化速率。

With the continuous development of renewable energy technology, microgrids system, as an effective means to access the grid as a distributed power supply,has attracted wide attention gradually.Because of the defects of single microgrid distributed power access capacity, poor anti disturbance capacity, reduce the electricity load stability.So the concept of microgrid is introduced, microgrid cluster use a plurality of microgrid coordination, overcomes the defect of single microgrid, optimizing the operation of the microgrid cluster in all aspets has become increasingly important.Firstly, forecasts on the solar power and the load, then the alternating direction method of multipliers （ADMM） is used to optimize the price, so the running cost of microgrid cluster is reduced to the minimum, and the microgrid can guarantee the reliability and power load key the quality of the whole system to improve the rate of optimization.
