摘要:

本文提出了一种可靠的能源调度框架的分布式能源(DER)的住宅区,以实现适当的日常用电量与最大的可负担的需求响应。可再生和不可再生能源资源可用于响应客户的需求,使用不同类别的方法来管理能源期间。最优运行问题是一个混合整数线性规划(MILP)研究基于模型的预测控制(MPC),以确定哪个可调度单元应在什么时间和在什么功率水平,同时满足实际约束。可再生能源(RES),特别是太阳能和风能,最近已经扩大了它们在电力电力系统中的作用。虽然它们是环境友好型和可访问的,但在其性能方面存在挑战性问题,例如处理与它们有关的可变性和不确定性。本研究探讨了这些系统的能源管理在三个互补的情况下。第一种和第二种情况分别适用于价格恒定和价格变化的市场。此外,第三种方案提出考虑的作用,可再生能源的不确定性,它的目的是补偿电力短缺使用不可再生资源。在一个住宅小区进行了24小时的测试,结果表明该方法具有降低运行成本的能力。

英文摘要:

This paper proposes a reliable energy scheduling framework for distributed energy resources (DER) of a residential area to achieve an appropriate daily electricity consumption with the maximum affordable demand response. Renewable and non-renewable energy resources are available to respond to customers' demands using different classes of methods to manage energy during the time. The optimal operation problem is a mixed-integer-linear-programming (MILP) investigated using model-based predictive control (MPC) to determine which dispatchable unit should be operated at what time and at what power level while satisfying practical constraints. Renewable energy sources (RES), particularly solar and wind energies recently have expanded their role in electric power systems. Although they are environment friendly and accessible, there are challenging issues regarding their performance such as dealing with the variability and uncertainties concerned with them. This research investigates the energy management of these systems in three complementary scenarios. The first and second scenarios are respectively suitable for a market with a constant and inconstant price. Additionally, the third scenario is proposed to consider the role of uncertainties in RES and it is designed to recompense the power shortage using non-renewable resources. The validity of methods is explored in a residential area for 24 hours and the results thoroughly demonstrate the competence of the proposed approach for decreasing the operation cost.
