Optimal Operation of Distribution System Operator and the Impact of Peer-to-Peer Transactions
AI总结：
本文提出含参与P2P交易产消者的配电系统运营商优化运行方法，研究发现符合特定模式的P2P交易不影响DSO内部调度与系统物理潮流，仅改变财务分配。
摘要：
点对点（P2P）能源交易作为一种去中心化方式，已成为更好利用分布式能源资源（DERs）的流行途径。为从系统运营商角度更好地管理这种用户侧去中心化模式，本文提出了一种面向配电系统运营商（DSO）的优化运行方法，该系统内部包含参与P2P交易的产消者。假设DSO是财务中立实体，负责汇总产消者完成P2P交易后的剩余电量与缺额需求，同时调度DERs并考虑网络完整性。本文研究了P2P交易对DSO优化运行的影响。结果表明，仅定义给定时间段内总电量的电量匹配型P2P交易，可能会影响DSO与批发市场之间的交换电量，但不会影响DSO的内部调度决策。不同水平的实时功率一致性可能导致配电网总剩余不同。作为电量匹配型P2P交易的特例，实时功率匹配型P2P交易的供电量与总剩余不受影响。换言之，若P2P交易遵循本文定义的模式，DSO可安全忽略此类交易。案例研究验证了上述结论，并进一步表明P2P交易不会影响整个系统的物理潮流，只会改变DSO与产消者之间的财务分配。
英文摘要：
Peer-to-peer (P2P) energy trading, commonly recognized as a decentralized approach, has emerged as a popular way to better utilize distributed energy resources (DERs). In order to better manage this user-side decentralized approach from a system operator's point of view, this paper proposes an optimal operation approach for distribution system operators (DSO), comprising internal prosumers who engage in P2P transactions. The DSO is assumed to be a financial neutral entity, holding the responsibility of aggregating the surplus energy and deficit demand of prosumers after their P2P transactions while dispatching DERs and considering network integrity. Impacts of P2P transactions on DSO's optimal operation have been studied. Results indicate that energy matching P2P trading where only the total amount of energy over a given period of time is defined may affect quantities of energy exchanged between the DSO and the wholesale market, but not internal dispatch decisions of the DSO. Different levels of real-time power consistency may lead to different total surpluses in the distribution network. For the real-time power matching P2P trading, as a special case of energy matching P2P trading, the provided energy and total surplus are not affected. In other words, DSO can safely ignore P2P transactions if they follow the format defined in this paper. Case studies verify these conclusions and further demonstrate that P2P trading will not affect physical power flow of the whole system, but the financial distribution between the DSO and prosumers.
