由于可再生资源发电的不稳定性和用户需求的时变性，用户的供需总是不均衡的。为了满足用户的需求，电能从一次发电输送到二次发电。它会造成很高的功率损耗。为了解决这一问题，本文提出了一种分布式算法。通过使用该算法，微电网能够与邻居进行电能交换，从而使智能电网的总网损降至最低。此外，与集中式算法相比，减少了通信开销(带宽)。通过计算机仿真表明，与集中式算法相比，该算法可以得到接近最优的结果，降低了微电网的平均网损，并显著降低了通信开销。
Because power generation of renewable resources are unstable and demands of the customers are time-varying, the supply power and demands of the customers are always unequal. To meet the demands of the customers, power is transmitted from primary power generation to secondary power generation. It will cause high power loss. To solve this problem, a distributed algorithm is proposed in this paper. By using the algorithm, the micro-grids are able to exchange power with their neighbors so as to minimize the total power losses of the smart grid. Moreover, communication overhead (bandwidth) is reduced, comparing with centralized algorithm. Through computer simulations, we demonstrate that the proposed algorithm can lead to near-optimal result for alleviating the average power loss per micro-grid and reduce the communication overhead significantly in contrast with the centralized approach.
