In Colombia, there is currently no regulation that specifies the metrics that must be taken into account in terms of the requirements of the control systems of a microgrid (MGCS Microgrid Control System). Starting from the previous problem, it was necessary to have a review article, which will present in a synthesized way the protocols and tests that must be carried out in the control systems, before their commissioning. The results show the basic functions that a control system must have. The functions are, dispatch and transition, these central functions are the basis for the correct operation of the MGCS and for this reason their respective tests are presented. Section 2 will address these functions and will present a series of tables describing the requirements, as well as their characteristics and metrics. Section 3 shows the tests, sets out the scenarios where they should be tested and the variables that should be measured. In section 4 the importance of communications within the MGCS is exposed, since the synergy of all assets, such as protections, distributed generation (DG distributed generation) and loads, depends on an excellent communication, for which a variety will be mentioned. of technologies to achieve this interaction between all these elements. It is intended that this reflection article presented serves in a practical way in terms of the application of the standards that served as the basis. This will allow future engineers who wish to implement this type of technology to have at hand a clear summary regarding the requirements of the control system, since they are the fundamental basis of the microgrid (MR).

Fault location in power distribution systems is an important aspect of power quality, in particular, in relation to power supply continuity. Currently, there are two clearly defined methods commonly used to locate faults, those which are based on the power system model and those which are based on knowledge. Fault location methods based on knowledge use information obtained from signals of voltage and current measured during fault situations, and normally require a considerable amount of fault registers to have a successful performance. This paper presents the modeling of a power distribution system and its protective relaying, settled in a fuse saving scheme. Using the described power system, it is possible to obtain a fault database by means of an event automatic generation using the Alternative Transient Program (ATP) and Matlab. The fault database can be used to perform different types of system analysis and in this specific case to solve the problem of fault location in power distribution systems using knowledge based methods. As a result, a data base which contains 930 different fault simulations on a 25 node test system was obtained. [ABSTRACT FROM AUTHOR]
