Abstract

This curricular integration work presents the design and construction of a 13.8 kV primary feeder scale emulator, connected to a time-varying load, simulating their daily demand curve, also applying the Peak Clipping technique. or peak demand cutting, as a Peak Shaving strategy. This technique is applied by connecting a load to an off-grid type inverter, which in turn is connected to a photovoltaic panel and a battery. Both will emulate the alternate font. This system is activated through the use of relays, when the measured power of the network reaches a specific limit, which is considered as the beginning of the peak of maximum demand. When entering activation, a load is disconnected from the network, and at the same time it is connected to the alternative source (PV panel and batteries). In this way, the effect of “shaving” the peak is obtained, smoothing the total demand curve supplied by the feeder. Once the requirement of the demand decreases from the limit value, the relay disconnects the alternative source of the load and reconnects it to the network. The total demand curves and the one obtained with the smoothing of the peak curve will be displayed on a screen, as well as the power and current measurements that circulate through the network (primary feeder) and those that circulate from the alternative source. Likewise, the project proposes three demand scenarios to verify the correct operation of the relays and the action of the alternate source at the moment that the maximum demand of the simulated feeder occurs.
