Assessment on Microgrid Reliability Applying Demand Side Management Scenarios

One of the problems with renewable resources inclusion is its intermittency. Its operation always oscillates due to weather conditions, day hour, and season of the year. This paper, using probabilistic distributions of solar radiation and wind speed, evaluates the impact of so Demand Side Management Strategies on the reliability indicators of a theoretical microgrid located in Barranquilla (Colombia). Initial results show a chance of occurring unbalance interruptions in months with low rate of wind speed, and rush hours. When Management Strategies are tested, it is shown decreases of outages and Not Supplied Energy in comparison with the base case. In addition, a switching system is implemented to disconnect several groups from the main bus in case of generation-demand unbalance. Criteria between reliability and billed energy are discussed to define a disconnection sequence.
