Abstract With the expansion of smart distribution networks, the effective utilization of distributed generation resources an‎d battery energy storage systems has become increasingly important. By generating power close to the load centers an‎d participating in ancillary services, these resources can significantly enhance network operating conditions. As their penetration level increases, the investigation of appropriate energy pricing schemes an‎d the coordinated management of these resources has emerged as a critical issue, since their operation directly affects both the technical performance of the network an‎d energy prices. In this thesis, the coordinated operation of distributed generation units an‎d battery energy storage systems is investigated using the Distribution Locational Marginal Pricing framework. In this approach, network losses, operational constraints, an‎d temporal variations are explicitly considered in the calculation of energy an‎d ancillary service prices. Employing this pricing mechanism enables a more accurate representation of the impact of local resources on energy prices an‎d establishes a meaningful link between the technical conditions of the network an‎d the economic behavior of distributed resources. To achieve a more realistic modeling of battery energy storage systems, a performance-based regulation payment mechanism is incorporated into their operational framework. Simulation results demonstrate that applying this mechanism leads to a more orderly charging an‎d discharging pattern of the batteries an‎d effectively prevents suboptimal operational behaviors. Moreover, the presence of distributed generation units, by supplying power in proximity to the load, reduces line power flows, decreases network losses, an‎d improves voltage profiles across different sections of the distribution network. The coordinated utilization of distributed generation an‎d battery energy storage systems facilitates proper power distribution an‎d enhanced network controllability, particularly during peak load periods. Overall, the obtained results indicate that the coordinated operation of distributed generation an‎d battery energy storage systems, when combined with locational pricing an‎d a performance-based regulation payment mechanism, can significantly improve both the technical an‎d economic performance of distribution networks. These findings can be effectively used in the analysis of distribution network operation an‎d in eva‎luating the role of local resources in energy an‎d ancillary service markets.
