Abstract

The rapid development of distributed energy resources (DER) in the distribution grid calls for novel control and coordination solutions. Optimal management of DER will enable end-users to decrease their electricity costs and provide crucial services to grid operators. In this paper, a decentralized Optimal Power Flow (OPF) model is used to locally coordinate DER in distribution networks, while considering the network constraints, in a distributed, transparent and secure fashion. To achieve that, a consensus-based distributed optimization algorithm is developed using the general form Alternating Direction Method of Multipliers (ADMM). To enable transparent and verifiable management of the network, the paper provides a comprehensive procedure for the implementation of the decentralized OPF on a private blockchain-smart contracts platform. The performance of the proposed framework is tested using real data from a case study in a residential neighborhood in Amsterdam with different varieties of DER. The implementation procedure on a blockchain-smart contracts platform may be adopted in other problems that require a smart contract to act as a virtual aggregator.

基于区块链的分布式配电网最优潮流

分布式能源在配电网中的快速发展要求新的控制和协调解决方案。对分布式电源的最佳管理将使最终用户能够降低电力成本，并为电网运营商提供关键服务。在考虑网络约束的前提下，采用分布式最优潮流(OPF)模型，以分布式、透明和安全的方式对配电网中的DER进行局部协调。为此，采用乘数交替方向法(ADMM)的一般形式，提出了一种基于共识的分布式优化算法。为了实现透明和可验证的网络管理，本文提供了在私有区块链智能合约平台上实施分散OPF的综合程序。本文使用阿姆斯特丹一个居民区的真实数据对所提出的框架的性能进行了测试，这些数据具有不同种类的DER。在其他需要智能合约充当虚拟聚合器的问题中，可以采用区块链智能合约平台上的实现过程。
