A system for collaborative energy management and control in a building, including an energy management controller, one or more occupant HMIs that supports two-way communication between building occupants and a facility manager, and between building occupants and the energy management controller, and a facility manager HMI that supports two-way communication between the facility manager and the building occupants, and between the facility manager and the energy management controller, in which the occupant HMI allows building occupants to provide temperature preferences to the facility manager and the energy management controller, and the facility manager HMI allows the facility manager to configure an energy policy for the building as a set of rules and to view occupants' aggregated temperature preferences, and the energy management controller determines an optimum temperature range that resolves conflicting occupant temperature preferences and occupant temperature preferences that conflict with the facility manager's energy policy for the building.

A method and system for enabling facility managers and occupants of commercial buildings to collaboratively define energy policy for building energy control is disclosed.

Disclosed is a power grid evolution simulation method applicable to large-scale new energy access. The power grid evolution simulation method comprises the following steps of 1, reading in system loadand energy prediction information; 2, determining whether voltage level upgrading is needed or not according to the substation density of the same voltage level in a region; 3, solving a power supplyplanning problem, and determining the number and expected output of newly built power plants; and 4, solving a power transmission network planning problem and determining a construction scheme of a circuit. By taking influence of the large-scale new energy access and new technological application to the power grid in the future into consideration, electric power, electric quantity, peak shaving and environmental protection constraints are introduced to the electric power system evolution model by drawing lessons from a power grid planning thought and by taking the minimum construction cost asan optimization target; a plurality of cutting-edge technology-based simplified models are established from the aspect of operation of the electric power system; finally, a solving method for the evolution model is proposed by combination with a heuristic rule and a plant growth simulation algorithm; and therefore, quantitative decision basis can be provided for an energy policy and an electric power strategy by adoption of the power grid evolution simulation method.

The invention discloses a server energy-saving method in a large-scale cloud data center, including a BP neural network energy-saving strategy training module, a monitoring data storage module, an energy-saving strategy storage module, a system overall monitoring and control module, an energy-saving strategy configuration management module, and an energy-saving strategy implementation The module automatically and efficiently adjusts the power consumption of the server group by setting the BP neural network energy-saving strategy model based on large-scale monitoring data sample training for the server group to achieve the overall energy-saving goal of the cloud data center. The present invention proposes an all-round, accurate and efficient energy-saving method and device for a cloud data center server group by associating a BP neural network energy-saving strategy model based on large-scale server load sample data training for the cloud data center server group. It has effectively improved the problem that most energy-saving policy settings are single, not accurate and reasonable, and cannot well adjust the energy consumption of the data center.

The present invention proposes a communication method with a dynamic wireless dormancy mechanism, which is used for setting a communication station to transmit time-division duplex frames, wherein each time-division duplex frame includes multiple subframes. The communication method includes: transmitting the ability to support a dynamic wireless dormancy mechanism to one or more communication devices; collecting at least one of service information, energy policy, energy state and interference policy to determine whether one or more presets are met the sleep condition; transmit one or more signaling messages to the one or more communication devices to implement a dynamic wireless sleep mechanism; and perform at least one of the following two: in the downlink subframe set to the sleep state, stop transmitting downlink services; and stopping receiving uplink services in the uplink subframes set to sleep state. The above embodiments can effectively reduce the energy consumption of the communication station and the communication device, and can reduce the signal interference between adjacent communication stations, so as to improve the performance of the communication system.
