“…In charging mode, EV consumes power from microgrid; in discharging mode, the power is fed back into the microgrid, which overcomes the scarcity of the local generation and meets the total load demand. The power consumed and discharged by EV at the charging station is formulated in [26] and has been reproduced here as (8), (9), and subject to operating constraints of voltage and current limit as per (10) and (11), respectively.…”

Communication plays a key role in the effective management of virtual power plants (VPPs). For effective and stable operation of VPPs, a reliable, secure, and standardized communication infrastructure is required. In the literature, efforts were made to develop this based on industry standards, such as the IEC 60870-5-104, OpenADR 2.0b and IEC 61850. Due to its global acceptance and strong object-oriented information models, IEC 61850 standard-based communication is preferred for smart grid operations, including VPPs. However, communication models based on IEC 61850 present cybersecurity and scalability challenges. To address this issue, this paper presents an eXtensible Message Presence Protocol (XMPP)-based IEC 61850 communication for VPPs. Firstly, a full mapping of IEC 61850 messages for VPP energy management is carried out. Secondly, XMPP-based single- and multiple-domain communications are demonstrated. Finally, a federation concept has been added to facilitate communication in multi-domain communication networks. These models show that a standard communication model can be implemented with IEC 61850 and XMPP, not only for VPPs but other wide-area communication implementations in smart grids. This not only facilitates plug-and-play (PnP) with easy component additions but secures smart grid communication against cyber-attacks.

“…A general architecture as well as the Information and Communication Technology (ICT) infrastructure for VPP operation were presented in [21]. A case was tested in [22] regarding the VPP communication system providing manual frequency restoration reserve service. Above works mainly focus on the physical construction of the VPP communication system, but the information to offer, the combination of information transmission and control schemes, and the resulting performance are also important issues that have not been formally studied.…”

The mushrooming of distributed energy resources turns end-users from passive price-takers to active marketparticipants. To manage massive proactive end-users efficiently, virtual power plant (VPP) as an innovative concept emerges. It can provide some necessary information to help consumers improve their profits and trade with the electricity market on behalf of them. One important information desired by consumers is the prediction of renewable outputs inside this VPP. Presently, most VPPs run in a centralized manner, which means the VPP predicts the outputs of all the renewable sources it manages and provides the predictions to every consumer who buys this information. We prove that providing predictions can boost social total surplus. However, with more consumers and renewables in the market, this centralized scheme needs extensive data communication and may jeopardize the privacy of individual stakeholders. In this paper, we propose a decentralized prediction provision algorithm in which consumers from each subregion only buy local predictions and exchange information with the VPP. Convergence is proved under a mild condition, and the demand gap between centralized and decentralized schemes is proved to have zero expectation and bounded variance. Illustrative examples show that the variance of this gap decreases with more consumers and higher uncertainty.

“…One of the new solutions of eliminating of DERs negative impacts is through the transformation of microgrid to VPP. VPP coordinates all DERs as in a single agent to integrate them into the grid without compromising the grid stability and reliability, adding many other additional benefits and opportunities to consumers, prosumers and grid operators [2].…”
