“…One main problem related to the DER is the possibility that part of the network can be powered even when disconnected [28,29], thus creating an unintentional island. However, unintentional island situations can be detected using frequency-dependent characteristics [17].…”

Microgrid and Distributed Energy Resources Standards and Guidelines Review: Grid Connection and Operation Technical Requirements

In this review, the state of the art of 23 distributed generation and microgrids standards has been analyzed. Among these standards, 18 correspond mainly to distributed generation while five of them introduce the concept of microgrid. The following topics have been considered: interconnection criteria, operating conditions, control capabilities, power quality, protection functions and reference variables. The revised national standards cover ten countries on four continents, which represents 80% of the countries with the largest installed renewable capacities. In addition, eight other relevant international standards have been analyzed, finding IEEE 1547 as the most comprehensive standard. It is identified a clear need to define a common framework for distributed energy resources (DERs) and microgrid standards in the future, wherein topics, terminology, and values are expressed in a manner that may widely cover the entire diversity in a way similar to how it has already been expressed at the network transport level by the ENTSO-E codes.

A passive RLC load is essential for conducting anti-islanding tests of inverter based grid connected distributed generator (DG) systems. A variable load is desirable if the tests need to be carried out over a range of operating conditions and on multiple DG based inverters of different ratings. Use of a physical load results in increased cost and space requirements, particularly when the rating of the DG under test increases. This paper presents power converter based impedance emulation technique to actively implement such a parallel RLC load. The dynamic and steady-state response of the load are synthesized using closed loop control of the passive load emulation converter (PLEC), such that the terminal behaviour of the converter matches the passive RLC load characteristics closely. The proposed technique is verified using simulations and experiments that consist of proposed PLEC working in tandem with a current controlled 3φ DG based inverter on a 5 kVA hardware prototype in laboratory.

“…So the distributed power system is required to have the ability to detect islanding condition, i.e., the situation in which distributed generators continue generating power when they are not connected to the utility grid. Usually, islandingdetection methods [1][2][3][4][5] can be classified into two main groups: local islanding detection methods and remote islanding detection methods.…”

“…(2) Remote islanding detection methods Remote islanding detection methods [2][6] [7] are also called communication based islanding detection methods. These methods can be divided in three groups, i.e., supervisory control and data acquisition based methods, methods that use the power line as a carrier for communications, and methods that monitor the device used to connect/disconnect from the grid.…”

Islanding detection is a necessary function for grid connected distributed generators. Usually, islanding detection methods can be classified as two catalogues: remote detecting methods and local detecting methods. Most of them have limitation and defects when they are applied in photovoltaic power stations. Recently synchronous phasor measuring units (PMU) is proposed to be applied for islanding detecting. Although the islanding detection method is supposed to be applied for traditional bulk power systems, it is also suitable for renewable generation power plants. To do this islanding detection will be implemented on central management unit of photovoltaic power station instead of on grid-tied inverters as traditionally. In implementing, the criteria of this method and the threshold of algorithm are needed to be optimized. This paper develops a test device which can optimize PMU-based islanding detection technology to validate the proposed islanding detection method applying in PV station. Then using simulation to discuss how to set a reasonable threshold for the researched islanding detection method applied in PV stations. Finally the paper provides a platform for the algorithm optimization.
