Abstract: It is described a control system for a microgrid for the production and distribution of electric power coming from multiple electric power sources of the intermittent and/or random and/or programmable and/or accumulation-system type, said microgrid control system being organized with a hierarchical control structure on two levels, comprising a first control level for power conversion systems (PCS) of electric power coming from said multiple electric power sources, a second control level for a microgrid controller (MC) adapted to cooperate with said first control level, said second control level being adapted to control electric power to be supplied to a distribution network (on-grid condition) and/or to be supplied as the primary generation to power up isolated loads (off-grid condition) and/or to control intelligent distributed electric power accumulation systems (ACC), said second control level for the microgrid controller (MC) comprising: a monitoring system (MON), adapted to interface with physical si

Abstract: A control system (50, 100) is for wind power plants including aerogenerators (10) provided with DC modular converters (40). The control system (50, 100) includes devices for receiving at least a voltage signal coming from a DC medium voltage line (MTDC) electrically connected to the converters (40) and a mechanical torque signal (CRIF) produced by the aerogenerators (10) and controls AC-DC conversion modules (40a?-40a??) of the plant. The modules have electronic devices driven by impressed voltage and producing on their outputs a respective partial continuous voltage (Vdci). For each aerogenerator (10) there are secondary control stages (100) and a single main control stage (50). Each of the secondary control stages (100) supplies control signals to a respective AC-DC conversion module (40a?-40a??) and is designed to keep the partial continuous voltage (Vdci) at a constant value.
