基于负荷聚集商的多家庭能量管理系统建模

Energy Management Modeling for Multiple Families Based on Load Aggregator Services

家庭能量管理系统可以合理规划家用电器的工作计划,降低家庭用户购电费用。然而单个家庭的负荷调节能力有限,难以做到最大化消纳光伏发电能量。本文提出了一种包含多个家庭用户的能量管理系统模型。通过负荷聚集商协调多个家庭用户的用电计划,从而降低用户的购电费用。在本模型的算例中,家庭用户购电费用降低的同时实现负荷聚集商的盈利,验证了本模型的可行性。通过算例中不同情境的对比,说明了本模型能够更多地消纳本地光伏发电,降低用户用电成本。

Home energy management systems（HEMS）can properly schedule domestic appliances and minimize the electricity purchasing costs.However,single HEMS limits load regulation ability,and it is hard for it to fully consume solar output.In this paper,an energy management system model is proposed,which involves multiple family clients.Load aggregator（LA）coordinates the power consumption of multiple families so that the electricity purchasing costs of families are minimized.At the same time,the LAs achieve their benefits,which verify the feasibility of proposed model.The comparison of different cases shows that proposed model can consume more local PV power,and reduce customer＇s electricity purchasing cost.
