Abstract: The disclosure relates to a method for localizing and quenching an arc in a PV generator of a PV system, wherein the PV generator includes at least two PV subgenerators. An arc quenching circuit is associated with each PV subgenerator. The method includes detecting an arc in the PV generator. Then, a probability value is determined for each of the PV subgenerators, wherein the probability value is correlated with a probability that the arc is located in the corresponding PV subgenerator. A sequence for activating the arc quenching circuits is then determined that is dependent on the determined probability values. Then, the arc quenching circuits are activated successively in the order of the determined sequence.

Abstract: A photovoltaic energy system includes a photovoltaic field configured to convert solar energy into electrical energy, cloud detectors configured to detect a cloud approaching the photovoltaic field, and a controller. The controller uses the cloud detectors to predict a disturbance in the electric power output of the photovoltaic energy system. The controller determines a time at which the disturbance is expected to occur and determines an amount by which the electric power output is expected to decrease. The controller can preemptively adjust the electric power output of the photovoltaic energy system in accordance with a predetermined ramp rate.

Abstract: An automatic battery recovery system includes a power conversion system (PCS) coupled between an AC power line and a DC power bus. The PCS is configured to convert between DC power from a battery system and AC power from the AC power line. An automatic recovery control (ARC) circuit is coupled in parallel with the PCS between the AC power line and the DC power bus. The ARC circuit is configured to convert AC power from the AC power line into DC power for powering the PCS based on a state-of-charge (SOC) of the battery system. The PCS includes an inverter coupled between the AC power line and the battery system and a digital signal processor (DSP) configured to command the inverter to charge the battery system from the AC power line while the DSP is being powered through the ARC circuit.

Abstract: A prediction calculator (643) uses a prediction model (633) to determine a predicted value of an amount of power to be generated by a power generation apparatus and a predicted value of an amount of power to be consumed by an appliance. The predicted values are associated with accuracy information. An operation planner (645) makes an operation plan using the predicted values determined by the prediction calculator (643), a user schedule included in user setting information (631), and an electricity rate table or weather forecast information. When the accuracy of the predicted value is lower than a predetermined reference, the operation planner (645) makes the operation plan only using other information without using the predicted value.
