Abstract
Electric Vehicles (EVs) are becoming one of the main answers to the decarbonization of the transport sector and Renewable Energy Sources (RES) to the decarbonization of the electricity production sector. Nevertheless, their impact on the electric grids cannot be neglected. New paradigms for the management of the grids where they are connected, which are typically distribution grids in Medium Voltage (MV) and Low Voltage (LV), are necessary. A reform of dispatching rules, including the management of distribution grids and the resources there connected, is in progress in Europe. In this paper, a new paradigm linked to the design of reform is proposed and then tested, in reference to a real distribution grid, operated by the main Italian Distribution System Operator (DSO), e-distribuzione. First, in reference to suitable future scenarios of spread of RES-based power plants and EVs charging stations (EVCS), using Power Flow (PF) models, a check of the operation of the distribution grid, in reference to the usual rules of management, is made. Second, a new dispatching model, involving DSO and the resources connected to its grids, is tested, using an Optimal Power Flow (OPF) algorithm. Results show that the new paradigm of dispatching can effectively be useful for preventing some operation problems of the distribution grids.
Highlights
Stopping climate change requires a revolution in the way we produce and consume energy
The issues are different in the two stages of the power system: most of the Renewable Energy Sources (RES)-based power plants are connected to the distribution grids (Dispersed Generation, DG) and all the EVs charging stations (EVCS) are connected to the distribution grids, the first impact is on the distribution level
It is worth to note that the study is focused on how the distribution grid could be affected by the increase of installed PV power, EVCSs and their management
Summary
Stopping climate change requires a revolution in the way we produce and consume energy. The common objective of the review process in all the European Countries is to test new ways for getting the necessary resources to guarantee the reliability of the whole power system, through a new form of dispatching service It includes taking in new entities, such as DG, MV and LV flexible end-users (such as EVCS) and their combinations, and involving in the dispatching functions the DSOs. In literature, many recent works are present on the impact on the transmission and distribution grids of RES-based DG and EVCS. Few papers deal with the problems related both to the distribution and transmission grids, linked to the DG and EVCS [26,27] In this context, the originality of the present work is to propose and test a new dispatching model on a real distribution system, in line with the reform that is in progress in Europe and in Italy [7], that implies a smart management of EVCSs, coordinated with DG, mainly RES-based.
