“…Distribution power systems are experiencing massive transformations that are buoyed by the increasing need to integrate more variable renewable-type distributed generations (DGs). This means that distribution grids will be equipped with the necessary tools to enable bidirectional power flows, which is contrary to their traditional setup [1][2][3][4][5][6][7]. Also, such a massive transformation needs to be accompanied by new operational schemes.…”

Electrical distribution system operators (DSOs) are facing an increasing number of challenges, largely as a result of the growing integration of distributed energy resources (DERs), such as photovoltaic (PV) and wind power. Amid global climate change and other energy-related concerns, the transformation of electrical distribution systems (EDSs) will most likely go ahead by modernizing distribution grids so that more DERs can be accommodated. Therefore, new operational strategies that aim to increase the flexibility of EDSs must be thought of and developed. This action is indispensable so that EDSs can seamlessly accommodate large amounts of intermittent renewable power. One plausible strategy that is worth considering is operating distribution systems in a meshed topology. The aim of this work is, therefore, related to the prospects of gradually adopting such a strategy. The analysis includes the additional level of flexibility that can be provided by operating distribution grids in a meshed manner, and the utilization level of variable renewable power. The distribution operational problem is formulated as a mixed integer linear programming approach in a stochastic framework. Numerical results reveal the multi-faceted benefits of operating distribution grids in a meshed manner. Such an operation scheme adds considerable flexibility to the system and leads to a more efficient utilization of variable renewable energy source (RES)-based distributed generation.

“…Despite their undeniable contribution, IEEE and CIGRE test networks are benchmark networks that can be used for general purposes but may hardly be adapted to assume some specific characteristics of a real given network. Alternatively, for demonstrating the effectiveness of their proposed solutions, many authors use test MV and LV distribution networks derived from real cases or ad hoc designed for emphasizing critical conditions that can be solved with their control and optimization algorithms, able to find the optimal planning alternative for the distribution network development, or the optimal scheduling of the distributed energy resources for minimizing operation costs, or the optimal position of devices useful to a wide range of purposes (see, for instance, References [3][4][5][6][7][8]). Few research projects proposed a repository of representative networks of a given national ambit (for instance in Italy [9] and in the UK [10]).…”

Many planning and operation studies that aim at fully assessing and optimizing the performance of the distribution grids, in response to the current trends, cannot ignore grid limitations. Modelling the distribution system, by including the electrical characteristics of the network (e.g., topology) and end user behaviors, has become complex, but essential, for all conventional and emerging actors/players of power systems (i.e., system and market operators, regulators, new market parties as service providers, aggregators, researchers, etc.). This paper deals with a methodology that, starting from publicly available open data on the energy consumption of a region or wider area, is capable to obtain reasonable load and generation profiles for the network supplied by each primary substation in the region/area. Furthermore, by combining these profiles with territorial and socio-economic information, the proposed methodology is able to model the network in terms of lines, conductors, loads and generators. The results of this procedure are the synthetic networks of the real distribution networks, that do not correspond exactly to the actual networks, but can characterize them in a realistic way. Such models can be used for all the kind of optimization studies that need to check the grid limitations. Results derived from Italian test cases are presented and discussed.

“…The uncertain nature of large-scale integration of variable renewable energy makes it technically challenging [19][20][21]. In general, the generation portfolio is designed in such a way that provides enough flexibility to cope with the variability of RES in the most efficient manner managing load forecast error and unplanned generation outages.…”

A power system can be defined as flexible if it can within economic and technological boundaries respond quickly and adequately to variations in supply and demand. The ongoing penetration of variable and intermittent renewable energy sources (RES) like wind and solar imposes additional and more critical requirement on power system flexibility. In this paper we propose a method to quantify these requirements based on the comparison of seven demand side parameters describing the statistical properties of the net load and the residual load of the referred power system. Each one of these parameters reflects a separate requirement on the available conventional generation in hourly and daily time scales—ramp up and ramp-down capabilities, technological minimum of generation, daily variation of generation. The proposed approach can be used to predict the requirements for generation flexibility according to the expected scenario of RES penetration in the future development of energy power system. It has been applied and integrated from the Bulgarian Transmission System Operator (TSO) which name is the Bulgarian Electricity System Operator (ESO).
