Optimal Microgrid–Interactive Reactive Power Management for Day–Ahead Operation

The replacement of conventional generation sources by DER creates the need to carefully manage reactive power maintaining system safe operation. principal trend is increase volume connected distribution network in coming years. Therefore, microgrid represents an alternative offer management due excellent controllability features embedded DER, which enable effective interaction between and network. This paper proposes a microgrid–iterative approach power-electronic converter based renewable technologies for day-ahead It designed be centralised control on local measurements, provides optimal dispatch minimise total energy losses inside maintain voltage profile within operational limits. proposed optimal-centralised contrasted against seven controls using techno-economic considering steady–state profile, losses, costs as performance metrics. Three different pricing are proposed. numerical results demonstrate microgrid–interactive most suitable day–ahead
