Abstract

Demand–response (DR) can provide the economic flexibility required to adapt a high proportion of renewable energy in the context of a smart grid. This paper proposes a transactive DR framework to enable the multi-time-scale proactive participation of demand-side flexible multi-energy resources. In this framework, the distribution system operator distributes the real-time DR request and the high renewable penetrated multi-energy prosumer aggregators provide the ancillary services based on their adjustable potential. To facilitate such multi-time-scale prosumer–operator interactions, a flexibility potential evaluation method is developed for the quantification and pricing of prosumer flexibility. The positive and negative flexibility potential of the demand-side prosumer aggregators are defined as deviations from the optimal pre-dispatch operation, which are further quantified using the aspects of flexible time and power. Based on the introduction of a flexibility pricing mechanism to identify the economically optimal ancillary service requirements, each prosumer aggregator performs an optimal real-time DR scheduling. Case studies over several DR schemes are performed to confirm the effectiveness and superiority of the proposed method on the economy and flexibility of the system.

智能电网背景下高可再生能源渗透性多能源消费者聚集器的交易性需求-响应框架
需求-响应(DR)可以提供在智能电网背景下适应高比例可再生能源所需的经济灵活性。本文提出了一个事务性DR框架,使需求方灵活的多能源资源能够在多时间尺度上积极参与。在该框架中,配电系统运营商分发实时DR请求,高可再生能源渗透的多能源生产消费者聚合器基于其可调节的潜力提供辅助服务。为了促进这种多时间尺度的生产-消费者-运营商互动,开发了一种用于生产-消费者灵活性量化和定价的灵活性潜力评估方法。需求侧生产-消费者聚合器的积极和消极灵活性潜力被定义为与最优预调度操作的偏差,并使用灵活的时间和功率方面对其进行进一步量化。在引入灵活性定价机制以确定经济上最优的辅助服务需求的基础上,每个生产-消费者聚合器执行最优的实时DR调度。通过对几种DR方案的实例研究,证实了该方法在系统经济性和灵活性方面的有效性和优越性。

期刊介绍: Applied Sciences (ISSN 2076-3417) provides an advanced forum on all aspects of applied natural sciences. It publishes reviews, research papers and communications. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible. There is no restriction on the length of the papers. The full experimental details must be provided so that the results can be reproduced. Electronic files and software regarding the full details of the calculation or experimental procedure, if unable to be published in a normal way, can be deposited as supplementary electronic material.
