Abstract: This disclosure is directed to a system for determining optimum setpoints for equipment in an industrial process. In some embodiments, the system does not use first-principles models to determine ideal setpoints. Instead, the system uses actual historical data and determines the setpoints at which the highest and/or longest key performance indexes were achieved according to some embodiments. In some embodiments, the system is able to save computer resources by reducing processing power through the use of a survival matrix as opposed to an iterative model. In some embodiments, the survival matrix is derived from statistical calculations on the historical data for KPI achieved timeframes.

Abstract: A Service Provider (SP) includes a controller that instructs several Producers (provide the electric energy) and Consumers (consume the electric energy) about the electrical energy. The controller selects one of the Producers as an Active Producer (AP) that provides a predetermined volume of the electric energy, one of a remainder of the Producers as a Passive Producer (PP) that adjusts a volume of provided electric energy to be, one of the Consumers as an Active Consumer (AC) that consumes a predetermined volume of the electric energy, and one of a remainder of the Consumers as a Passive Consumer (PC) that adjusts a volume of consumed electric energy, and the controller instructs one of Passive Subscribers (either the PP or the PC) to adjust the electric energy, so as to mitigate a difference between a total supply volume and a total demand volume.

Abstract: An energy management system includes energy storage, a load, a guide server and a local controller. The energy storage is configured to be charged and discharged, and connected to a grid line, the grid line being supplied with power from an outside power generator. The load is configured to operate with consuming power supplied via the grid line. The guide server is configured to predict conditions of the energy storage, the load and the grid line and to generate a directive corresponding to the prediction, and outputs the generated directive. The local controller is configured to control charging and discharging of the energy storage based on or guided by the directive generated in the guide server.

Abstract: System and methods for performing microgrids cooperation by optimal coalition formation in a distribution network are disclosed. A Microgrid Cooperation Module (MCM) is designed for utility EMS. MCM contains a coalition formation unit and an energy exchange decision unit. Furthermore, a communication protocol for energy exchange between two microgrids is designed. The coalition formation unit applies an innovative hierarchical coalition formation algorithm to provide optimal coalition for real time operation. The real time energy status of microgrids will be provided to coalition formation unit which will determine the coalitions (given a distance threshold) among microgrids to minimize the power loss. Energy exchange decision unit then determine actual energy transfer between pairs of microgrids within a coalition. Upon receiving the energy transfer information through a communication channel, the microgrids will start communicating and process energy transfer.

Abstract: One of the features of the invented method is that it adds to the scenario selection criteria the impact on the control command of the single scenarios. If necessary it takes also into account the performance achieved during single scenario optimization and combines scenario describing space information with single scenario optimization results space information. By using reduced scenarios (subset) an overall optimization procedure based on the subset can be established. If results are not satisfactory from the performance or constraints point of view a new iteration is initiated.

Abstract: A plurality of subsystems (21, 22, 23) have one or more internal states. A plurality of local optimizers (11, 12, 13) control the corresponding subsystems based on the internal states thereof and data exchange due to a coupling between the subsystems, respectively. A mediator (10) monitors outputs (y1, y2, y3) and/or some internal states of the plurality of subsystems (21, 22, 23) and controls operations of the plurality of local optimizers (11, 12, 13) based on the internal states and/or outputs thereof. Each of a first subsystem and a second subsystem is one of the plurality of subsystems (21, 22, 23). A first internal state that is the close to the second subsystem in the first subsystem is affected by a second internal state that is close to the first subsystem in the second subsystem, or the first and second subsystems share a common resource.

Abstract: [Problem] To provide a distributed power supply system having a plurality of micro-grids and capable of operating at low energy cost, a station control device, a control method, and a storage medium in which a control program is stored. [Solution] A station control device controls: the starting up and stopping of a distributed power supply for supplying power to a load that consumes power; the distributed power supply and said load; and the opening and closing of a switch for connecting another power supply controlled by another station control device. The station control device controls the switch and the distributed power supply on the basis of: demand power information indicating power consumed by the load; fuel efficiency information indicating the output-fuel consumption characteristics of the distributed power supply; the demand power information of another load to which another distributed power supply supplies power; and the fuel efficiency information of the other distributed power supply.
