本文讨论了一种基于市场的微电网联营体策略，以实现在配电市场中的最优电力交易。随着分布式能源和移动电源在配电系统中的渗透率不断提高，配电系统运营商面临着更高的压力，对协调控制策略提出了更高的要求。分配系统运营商对这样的分布式资源具有有限的可见性和控制。为了降低系统的复杂性，提高电力市场运行的效率，提出了一种分散式联营体策略，通过市场机制实现MG与配电系统的集成。基于市场的互动程序之间的MG和DS的MG价格制定者，以找到一个最优的出价/报价策略有效地开发。为了实现所有实体之间的市场均衡，我们最初铸造这个问题作为一个双层规划问题，其中上层是一个MG最优调度问题和下层提出的DEM清除机制。将所提出的双层模型转化为一个单一的混合整数模型，从而更容易求解。该问题考虑了MG竞争对手报价和需求的不确定性。从一个修改的IEEE 33节点配电系统的解决方案的结果进行了介绍和讨论。最后，得出了一些结论，并进行了检验。
This paper discusses a market-based pool strategy for a microgrid (MG) to optimally trade electric power in the distribution electricity market (DEM). The increasing penetration levels of distributed energy resources and MGs in distribution system (DS) stress distribution system operator and require higher levels of coordinated control strategies. The distribution system operator has limited visibility and control over such distributed resources. To reduce the complexity of the system and improve the efficiency of the electricity market operation, we propose a decentralized pool strategy for an MG to integrate with a distribution system through a market mechanism. A market-based interactions procedure between MGs and DS is developed for MGs as price makers to find an optimal bidding/offering strategy efficiently. To achieve a market equilibrium among all entities, we initially cast this problem as a bi-level programming problem, in which the upper level is an MG optimal scheduling problem and the lower level presents a DEM clearing mechanism. The proposed bi-level model is converted to a single mix-integer model, which is easier to solve. Uncertainties associated with MG's rivals’ offers and demands’ bids are considered in this problem. The solution results from a modified IEEE 33-Bus distribution system are presented and discussed. Finally, some conclusions are drawn and examined.
