  • 서울과 수도권 지역에서는 집을 사려는 사람보다 팔겠다는 사람이 주를 이룬다. 살 사람은 적은데 팔 사람이 많다 보니 수급 불균형에 따른 가격 하락이 이어지는 실정이다. 하지만 집값을 자극할 만한 변수가 생기거나 아파트 공급이 차질을 빚는다면 언제든지 수급불균형에 따른 집값이 들썩일지 모른다.

  • Recently, due to the introduction of distributed energy resources, the optimal resource allocation problem of the power network is more and more important, and the distributed resource allocation method is required to process huge amount of data in large-scale power networks. In the optimal resource allocation problem, many studies have been conducted on the case when the supply-demand balance is satisfied due to the limitation of the generation capacity of each generator, but the studies considering the supply-demand imbalance, that total demand exceeds the maximum generation capacity, have rarely been considered. In this paper, we propose the consensus-based distributed algorithm for the optimal resource allocation of power network considering the supply-demand imbalance condition as well as the supply-demand balance condition. The proposed distributed algorithm is designed to allocate the optimal resources when the supply-demand balance condition is satisfied, and to measure the amount of required resources when the supply-demand is imbalanced. Finally, we conduct the simulations to verify the performance of the proposed algorithm.
