| contents | 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. |
