Problem While simulating a grid connected PV system using co-simulation among PSIM and SIMULINK i was getting error. The error stated that Algebraic state in algebraic loop containing 'SCMPPT_sensorless_v4_buckboost_ok/Product3' computed at time 0.0005 is Inf or NaN. There may be a singularity in the solution. If the model is correct, try reducing the step size (either by reducing the fixed step size or...
Solar PV modules are typically connected to an dc-dc converter for ensuring the operation at maximum available power. While the research work has shown us the possibilities of using different kinds of dc-dc converters, following three basic topologies are still widely used. Solar PV modules are typically connected to an dc-dc converter for ensuring the operation at maximum available power. While the research...
Reading research papers is must for carrying out updated research that too in right direction. When I was stuck for almost two months on the design issues related to grid-connected PV systems I worked hard to get my issues resolved. While reading and reading and reading I read thesis reports, research papers and a lot of online articles. However, the following papers helped...
Problem I encountered a strange problem while co-simulation of a PV grid connected inverter. The problem was that for simulation time less than 2 sec, the simulation results were ok. For time more than 2.5 sec the results were bad. See these figures. ...
