“…Prior to and during the development of 1547, numerous documents delineated major issues, obstacles, and approaches to an orderly transition to the interconnection of DR with the grid [1][2][3][4]. The 1547 work group minutes [5] and resource documents include voluminous amounts of technical information, documentation of standardized feedback, reviews of individual clauses/sections, recommended rewording, and reviewer rationales.…”

“…Ferroresonance can lead to significant overvoltages; peak voltage may reach 3-4 pu [1], [20]. Ferroresonance may occur when both induction and synchronous machines are connected to the circuit [21].…”

“…4) Nonlinearity must be provided with a coupling transformer core [22]. A large number of theoretical studies and simulations have been carried out by many researchers; a few papers have been published on the ferroresonance phenomenon in distribution networks in the presence of DG units [20]- [24]. These papers have not carefully examined occurrence of ferroresonance phenomenon due to autonomous operation of DG, and this problem has been only introduced in these papers.…”

This paper reports on ferroresonance phenomenon in distribution networks after the islanding of a distributed generation (DG) unit. Five coupling transformer configurations in synchronous machine-based DG are used to analyze and discuss occurrences of ferroresonance. PSCAD/EMTDC software was used to simulate the various configurations to collect data for analysis. Chaos theory was used to analyze the simulation results in a MATLAB environment in order to understand the type of ferroresonance present. This paper supports that synchronous machine-based DG units could be highly prone to occurrence of ferroresonance phenomenon after islanding with differences observed among the five configurations studied. This paper confirms that a groundedwye/delta connection is highly prone to ferroresonance and a delta/grounded-wye connection avoids ferroresonance when a DG unit becomes an island. Résumé-Ce travail de recherche concerne le phénomène de ferrorésonance dans les réseaux de distribution après l'isolation d'une unité de production distribuée (PD). Cinq configurations de transformateurs de couplage de PD basés sur les machines synchrones sont utilisées pour analyser et discuter des occurrences de ferrorésonance. Le logiciel PSCAD/EMTDC a été utilisé pour simuler les différentes configurations pour l'acquisition des donnéespour l'analyse. La théorie du chaos a été utilisée pour analyser les résultats de la simulation avec MATLAB pour mieux comprendre la ferrorésonance en question. Cet article prouve que les unités PD synchrones basées sur les machines synchrones après l'isolation pourraient être sujettes à l'apparition du phénomène de ferrorésonance avec des différences observées entre les cinq configurations étudiées. Ce document confirme que la connexion Wye-Delta liée à la masse peut avoir lieu quand une unité PD est isolée et une connexion delta/masse évite la ferrorésonance quand une DG est isolée aussi.

“…Overvoltages: Several types of overvoltages can occur in a distribution system with local generation (ground-fault overvoltage, load-rejection overvoltage, ferroresonance [31], [32]). There are, on the other hand, overvoltages (e.g., lightning) not caused by generation whose effect on distribution equipment, including generators, can be very significant.…”

Distribution software packages were primarily designed for analyzing radial systems with very limited capabilities for representing distributed resources (DR). Software manufacturers are presently updating and expanding the capabilities of their tools. The challenges, however, are many, since the new tools should be able to represent a wide range of power component models, efficiently compute steady-state and transient unbalanced operating conditions, or cope with DR interconnections whose design cannot be anticipated yet. This paper summarizes the main types of studies related to planning, analysis, and design of distribution networks, analyzes the models required for representing distributed resources, and discusses the future capabilities of distribution software packages. This paper includes test cases that illustrate some of the studies related to planning, analysis, and design of distribution networks with penetration of DR.
