“…As described in [113], a current limitation would protect the components without violating fixed limits, set by the technical requirements of each converter. An adaptive overcurrent protection for distribution networks has been developed in [228,229]. A neural network based overcurrent protection approach is shown in [230].…”

“…The conventional distribution networks are a dual structure system that consist of substations and loads, with the power flowing from the grid to consumers. Since there are no distributed generations (DGs) connected into the grid, this kind of network can be called a passive distribution network (PDN) [4]. An active distribution network (ADN) is a ternary structure system, which consists of DGs, substations and loads, where a flexible network topology is employed to manage power flows and achieve the proactive regulation of DGs [5].…”

Due to high penetration of renewable energy recourses in the existing distribution network, the protection system faced a new challenge. This paper presents an adaptive overcurrent protection scheme for active distribution network ADN enhanced by real time measurement gathered from micro phasor measurement unit 𝜇PMU. The 𝜇PMU measurement is used in this paper to estimate the network topology of the ADN. The proposed scheme has been tested and validated using MATLAB programing environment. The simulation results demonstrate the effectiveness of the proposed adaptive protection scheme.

“…According to the voltage information, Reference (19) compares the positive sequence component of bus voltages before fault with the fault component of feeder positive sequence current to realize the distribution network protection. The above references need to provide the voltage information, which is difficult to be realized in engineering practice [20].…”

According to the latest grid-connected standard, the failure of IIDG (inverter-interfaced distributed generator), represented by wind power and photovoltaic power, is characterized by strong nonlinear output. Therefore, the protection scheme based on the traditional fault characteristics is difficult to be applied to the distribution network with high permeability IIDG access. Based on the low voltage traversing operation characteristics of PQ control strategy IIDG, the work analyzed the distribution characteristics of positive sequence fault components in distribution network, and proposed a pilot protection scheme for distribution networks based on the comparison of current amplitudes on both sides of line. This scheme not only reduced the strict requirement of pilot protection for synchronous sampling of communication facilities, but also eliminated the influence of load current. Moreover, it had good practicability and economy without the protection and cooperation with other components. At the same time, in order to avoid the misoperation of amplitude ratio protection criterion for non-fault line due to the existence of unmeasured load branches, the distribution characteristics of node branch current abrupt changes were used to establish the auxiliary criterion for node-branch current mutation. It solved the action dead zone of the ratio protection criterion. Finally, the feasibility of the proposed protection principle was verified by DIgSILENT simulation.
