Abstract:
It is an object of this disclosure to provide an efficient continuous power system that may be deployed quickly and at low cost to a variety of destinations. The containerized nature of the presently disclosed system may allow these advantages to be attained. The disclosed system is particularly well suited for deployment in data center applications, but one of ordinary skill will recognize that it may be useful in a variety of situations.
Abstract:
An energy distribution may include a server and one or more databases. The system may communicate with an energy provider to receive energy provider data, at least one information collector to receive information collector data such as individualized energy usage data, customer preferences, and customer or location characteristics, and the one or more databases for receiving data for optimization. The system may calculate a cost of service or avoided cost using at least one of the individualized energy usage data and a system generation cost at a nearest bus. The system may also forecast individualized demand by end-use, individualized demand by location, energy prices, or energy costs. The system may optimize energy distribution, energy use, cost of service, or avoided cost using the forecasted individualized demand by end-use, the forecasted individualized demand by location, the forecasted energy prices, and the forecasted energy costs.
Abstract:
The invention is directed to an optical network terminal (ONT) for use in a passive optical network (PON) that provides reliable battery status reporting and, optionally, remote monitoring and configuration of an uninterruptible power supply (UPS) unit. In particular, the UPS unit provides power to the ONT via a power line and transmits data to the ONT via the power line. Generally, the described invention supports one-way or two-way communication of status, alarm, and configuration signals using a single power line. Specifically, such signals may be transmitted over the power line by inserting a carrier frequency, such as carrier frequency of approximately 1 MHz, onto the power line. In this manner, the invention may provide a simple battery status monitoring system while also reducing the cost of installation.
Abstract:
A system for providing power to telephone handsets (4) and other appliances that are connected to a LAN switch (1). Telephone handsets (4) with built-in Ethernet interfaces can be used to create an enterprise voice communications network which emulates the functions of a standard voice private branch exchange (PBX) switch. The disclosed LAN switch (1) advantageously provides power directly to LAN telephone instruments within the system. The disclosed system may include a means (2) for adding a power system to an existing LAN switch (1) so that remote telephone handsets (4) can receive power from a central location. Alternatively, power equipment may be integrated into LAN switch itself. The primary benefit of a central power system (2) for Ethernet appliances is that is more convenient to provide back-up power, so that the attached appliances can continue to operate in the event of a power failure.
Abstract:
A fail-safe lighting system which includes provision for setting priorities or sequences of operation for different lights or sets of lights (68, 72). When normal power (50) is interrupted, all or a selected number of lights remain lit and/or are dimmed, thus providing a first level of illumination during a predetermined period of time. However, when a selected interval of time has elapsed and the level of charge remaining on the battery (56) or batteries which supply power during the interruption decreases, preselected one or ones of the lights are progressively dimmed or disconnected from the battery according to a predetermined schedule. Thus, the time during which one or more extremely critical lights remain lit can be substantially extended without depleting the charge on the battery.
Abstract:
A central plant that generates and provides resources to a building. The central plant includes an electrical energy storage subplant configured to store electrical energy purchased from a utility and to discharge the stored electrical energy. The central plant includes a plurality of generator subplants that consume one or more input resources. The central plant includes a controller configured to determine, for each time step within a time horizon, an optimal allocation of the input resources and the output resources for each of the subplants in order to optimize a total monetary value of operating the central plant over the time horizon. The total monetary value includes revenue from participating in incentive-based demand response programs as well as costs associated with resource consumption, equipment degradation, and losses in battery capacity.
