The current energy crisis calls for a rapid transition to renewables. Solar photovoltaics (PV) is the key component of the future energy system and a majority of PV systems are installed on rooftops in Europe. This article studies the business case of prosumers, i.e., consumers who produce part or all of their electricity with PV. The levelized cost of PV electricity is compared with the average value of PV electricity for the prosumers in residential, commercial, and industrial installations in Finland, Germany, France, Italy, and Spain with different self-consumption (SC) and weighted average cost of capital rates. Prosumer business cases are positive in every studied market segment and country, especially for industrial PV systems with 100% SC where a payback time of less than 4 years can be achieved. The sensitivity of payback time on key input parameters is also studied. Reasonable cost of capital and adequate SC of PV generation remain the key elements for attractive prosumerism. 相似文献

Smart living labs such as the one located in Fribourg (Switzerland) focus on improving wellbeing and furthering knowledge related to building the district of the future on a technical and social level. Therefore, smart living labs represent an experimental platform/space where sustainable production and consumption strategies can be tested in a protected environment. A significant change in the socioeconomic production and consumption sphere can be expected by the rise of the so-called energy prosumer. Accordingly, this article presents an interactive model for the experimental investigation of energy prosumer behavior. In this context, two potential experiments on investment and trade decisions are briefly outlined. Since (behavioral and economic) experiments are usually conducted under controlled conditions in experimental labs involving mainly undergraduate students, the presented interactive model is flexible and mobile, providing the advantage to conduct experiments nearly everywhere involving everyday citizens. 相似文献

随着局域能源市场中分布式能源的大量接入和电力系统运行方式的逐渐转变,具有电能生产/消费行为的产消者得到了广泛关注与研究。在此背景下,为提高小规模能源在局域能源市场中的就地消纳能力,设计了一种面向局域能源市场中多产消者的点对点(P2P)日前市场交易框架。在局域能源市场建立了P2P市场交易平台,并对产消者的基本特征进行了归纳分析,提出了典型的产消者组合类型;在产消者层面,采用供给函数均衡模型对产消者竞价行为进行建模,确立了含多产消者的P2P交易平台参与局域能源市场交易;采用连续双边拍卖机制对产消者之间进行P2P匹配,并确定交易过程中的拍卖价格和交易价格。最后,通过算例验证了所提P2P交易框架的有效性。 相似文献

This paper investigates a double auction-based peer-to-peer (P2P) energy trading market for a community of renewable prosumers with private information on reservation price and quantity of energy to be traded. A novel competition padding auction (CPA) mechanism for P2P energy trading is proposed to address the budget deficit problem while holding the advantages of the widely-used Vickrey-Clarke-Groves mechanism. To illustrate the theoretical properties of the CPA mechanism, the sufficient conditions are identified for a truth-telling equilibrium with a budget surplus to exist, while further proving its asymptotical economic efficiency. In addition, the CPA mechanism is implemented through consortium blockchain smart contracts to create safer, faster, and larger P2P energy trading markets. The proposed mechanism is embedded into blockchain consensus protocols for high consensus efficiency, and the budget surplus of the CPA mechanism motivates the prosumers to manage the blockchain. Case studies are carried out to show the effectiveness of the proposed method. 相似文献

分布式资源的增长使得电力用户逐步从消费者转变为产销者。主要针对产销者点对点(peer-to-peer,P2P)交易全分散式出清问题开展研究。首先,以产销者总成本最小为目标,综合考虑过网费与网络约束,建立产销者P2P交易模型。其次,基于多阶段优化理论将P2P交易模型转化为全分散式优化模型,并以节点累积偏移电压和线路累积使用容量为状态变量,清晰地刻画每一对交易对配电网运行的影响情况。接着,利用对偶动态规划(dual dynamic programming,DDP)进行求解。为了提高求解效率,采用帕累托最优割技术对DDP进行改进,以减少冗余Benders割的产生,在保证算法精度的同时提高其收敛速度。最后,通过算例分析验证了所提方法的有效性。

Among household electricity end users, there is growing interest in local renewable electricity generation and energy independence. Community‐based and neighborhood energy projects, where consumers and prosumers of electricity trade their energy locally in a peer‐to‐peer system, have started to emerge in different parts of the world. This study investigates and compares the costs incurred by individual households and households organized in electricity trading communities in seeking to attain greater independence from the centralized electricity system. This independence is investigated with respect to: (i) the potential to reduce the electricity transfer capacity to and from the centralized system and (ii) the potential to increase self‐sufficiency. An optimization model is designed to analyze the investment and operation of residential photovoltaic battery systems. The model is then applied to different cases in a region of southern Sweden for year 2030. Utilizing measured electricity demand data for Swedish households, we show that with a reduced electricity transfer capacity to the centralized system, already a community of five residential prosumers can supply the household demand at lower cost than can prosumers acting individually. Grouping of residential prosumers in an electricity trading community confers greater benefits under conditions with a reduced electricity transfer capacity than when the goal is to become electricity self‐sufficient. It is important to consider the local utilization of photovoltaic‐generated electricity and its effect on the net trading pattern (to and from the centralized system) when discussing the impact on the electricity system of a high percentage of prosumers. 相似文献

随着具有源荷二重属性的产消者占比日益提高,如何建立适合产消者的有效交易机制,激励其能源消纳是目前亟待解决的问题。针对该问题,提出区块链技术下的产消者与运营商的集群交易模型,将区块链技术量化到产消者的用电行为上。考虑到产消者集群内各主体独立,电价制定和电量调度存在先后次序,采取Stackelberg博弈理论寻求最优交互策略,并通过区块链更新求解过程中的交互信息。仿真结果表明：通过制定内部电价,能够提升集群内的光伏自消纳水平,同时在区块链技术下聚合优化集群内资源,可以有效提高产消者的用电效益与运营商的收益。进一步,结合光伏上网电价退坡政策,再次验证了所提模型的有效性。 相似文献

随着分布式资源接入技术和可交易能源市场的快速发展,海量异构多能产消者电热能源共享和源荷强不确定性给联盟能量管理带来极大挑战。基于此,提出一种基于核仁聚类估计和数据驱动分布鲁棒优化的海量异构多能产消者联盟能量管理策略。该方法以联盟及个体在多重不确定性影响下的社会福利最大为目标,建立了考虑电热网络动态差异性的海量产消者能量管理模型,以解决联盟能量管理可扩展性、公平性和隐私性难以兼顾的问题。另外,考虑到核仁计算的复杂度和源荷不确定性的不利影响,分别提出了基于高斯混合聚类的核仁估计方法和基于数据驱动Wasserstein距离的分布鲁棒优化模型,实现了模型求解速度与精度的均衡。算例结果表明,所提方法有效提升了产消者联盟在多重不确定性影响下的社会福利,实现了联盟能量管理可扩展性、公平性和隐私性的均衡,促进了更多的产消者参与本地能源点对点(peer-to-peer, P2P)交易。 相似文献
