Smart Grids are electricity networks that use digital technology to co-ordinate the needs and capabilities of all generators, grid operators, end users and electricity market stakeholders in such a way that it can optimize asset utilization and operation while maintaining system reliability, resilience and stability. However, Smart Grids are increasingly proposing a much more distributed architecture with the integration of multiple Distributed Energy Resources (DERs) that demand different control and protection schemes. In that sense, the implementation of standards such as IEC 61850 and the integration with Ethernet-based communication networks provide novel tools to manage DER efficiently. This paper analyses the potential usage and benefits of ANSI 67/67N protection in combination with Generic Object Oriented Substation Event (GOOSE) communication service, from the standard 61850 of the International Electro-technical Commission (IEC), for providing adaptive network protection, specifying the configuration and implementation and exposing the obtained results.

Abstract:In an electrical power system, the coordination of the overcurrent relays plays an important role in protecting the electrical system by providing primary as well as backup protection. To reduce power outages, the coordination between these relays should be kept at the optimum value to minimize the total operating time and ensure that the least damage occurs under fault conditions. It is also imperative to ensure that the relay setting does not create an unintentional operation and consecutive sympathy trips. In a power system protection coordination problem, the objective function to be optimized is the sum of the total operating time of all main relays. In this paper, the coordination of overcurrent relays in a ring fed distribution system is formulated as an optimization problem. Coordination is performed using proposed continuous particle swarm optimization. In order to enhance and improve the quality of this solution a local search algorithm (LSA) is implanted into the original particle swarm algorithm (PSO) and, in addition to the constraints, these are amalgamated into the fitness function via the penalty method. The results achieved from the continuous particle swarm optimization algorithm (CPSO) are compared with other evolutionary optimization algorithms (EA) and this comparison showed that the proposed scheme is competent in dealing with the relevant problems. From further analyzing the obtained results, it was found that the continuous particle swarm approach provides the most globally optimum solution.

“…By reviewing the previous papers and researches, coordination of DOCRs can be summarized as follows: Adaptive coordination: In adaptive approaches, coordination of relays varies according to the changes in network. In this method, relays are adjusted in 3 ways: centralized, decentralized, and hybrid . In the centralized approach, in case of any change (change in the status of DG, loads, network structure, etc.…”

Summary Penetration of distributed generations in distribution networks (active distribution networks) has resulted in some problems such as change in short circuit level and direction of fault current flow. Such conditions may cause some relays to malfunction. In this paper, a method for coordinating directional overcurrent relays in active distribution networks taking uncertainties into consideration is proposed. These uncertainties include changes in operation conditions, changes in fault conditions, error in measuring equipment, and outage of distributed generations. Therefore, an optimization frame with new variables is presented, which can be used to create different characteristic curves. Taking uncertainties into account causes the number of constraints to increase and the problem of coordination of directional overcurrent relays to become more complicated. Thus, a two‐step approach is used to solve this problem. In the first step, an algorithm is used to form the constraints of the problem, then, in the second step, a hybrid optimization algorithm consisting of the cuckoo search algorithm and linear programming is proposed. The simulation results for active radial and meshed distribution networks are presented to demonstrate the effectiveness of the proposed approach.
