论文摘要
在这项研究中,提出了一个合作游戏模型,以安排多微晶(MMG)系统的日前操作。在拟议的模型中,安排微电网以实现多微晶系统成本的全局最佳。最低成本是通过彼此的微电网交易来实现的。此外,模型中还实施了基于价格的需求响应,以为消费者建立降低成本的机会。应用沙普利值,MMG系统的最佳成本是在微电网之间公平分配的。为了提高结果的置信度,数据不确定性已纳入模型。模型中应用了可再生产出,需求和与主要电网交易的价格的不确定性。提出的模型是作为混合整数线性编程问题开发的,其效率在包含三个微电网的标准测试系统上进行评估。将MMG系统的成本与微电网形成合作游戏时的成本与微电网不相互交易的孤立状态进行比较。结果表明,与隔离模式相比,使用所提出的合作模型降低了MMG系统的成本。同样,微电网1,微电网2和微电网3的成本分别提高了2.4%,2.7和11.8%。因此,所有微电网都有参与合作游戏的动机,并且在合作游戏中,总成本和每个微电网成本都得到了改善。
In this study, a cooperative game model is presented to schedule the day-ahead operation of multi-microgrid (MMG) systems. In the proposed model, microgrids are scheduled to achieve a global optimum for the cost of the multi-microgrid system. The minimum cost is achieved by transactions of microgrids with each other. Also, price-based demand response is implemented in the model to build a cost-reducing opportunity for consumers. Applying Shapley value, the optimum cost of the MMG system is fairly allocated between microgrids. To enhance the confidence level of results, data uncertainties are incorporated into the model. The uncertainties of renewable outputs, demand, and prices of trading with the main grid are applied in the model. The presented model is developed as a mixed-integer linear programming problem, and its efficiency is evaluated on a standard test system containing three microgrids. The cost of the MMG system when microgrids form a cooperative game is compared with the isolated status that microgrids do not transact energy with each other. The results indicate that the cost of the MMG system is declined using the proposed cooperative model in comparison with the isolated mode. Also, the cost of microgrid 1, microgrid 2, and microgrid 3 are improved by 2.4, 2.7, and 11.8%, respectively. Therefore, all the microgrids have an incentive to participate in the cooperative game, and both the total cost and each microgrid cost are improved in the cooperative game.
