摘要： A method of self-healing power grids after power outages includes providing an Adaptive Restoration Decision Support System (ARDSS) for generating a restoration solution using static and dynamic input data from power generator(s) powering transmission lines, from the transmission lines and loads. At a beginning of a restoration period a two-stage problem is solved including a first and second-stage problem with an optimal planning (OP) function as a mixed-integer linear programming (MILP) problem using initial static and dynamic data to determine start-up times for the power generator and energization sequences for transmission lines involved in the power outage. Only the second-stage problem is again solved with an optimal real-time (OR) function using the start-up times and energization sequences along with updated static and dynamic data to determine operating parameters for the grid. The restoration solution is implemented over restoration time steps until all loads involved in the power outage are recovered.

摘要： A hybrid electrical power generation system is providing for powering a power consuming system including first and second loads. The hybrid system includes first and second primary generator sets, a redundant generator set, and a utility connection. Each generator set includes an engine mechanically coupled to an electrical power generator. The first primary generator set is fueled by a first fuel and is configured to supply electrical power to the first load, and the second primary generator set is configured to supply electrical power to the second load. The redundant generator set is fueled by a second fuel and is configured to supply electrical power to at least one of the first and second loads. The utility connection is configured to supply electrical power from a utility power grid to the first and the second loads. A controller controls distribution of electrical power to the first and second loads.

摘要： The present invention is directed, in part, to electrical components and methods of use associated with such components. In particular, the invention relates to an electrical device and improved method of back feeding energy generated from alternative energy devices such as solar panels, wind turbines, fuel cells, electrical generators and other alternative energy sources, to the utility without the necessity of installing a sub panel or replacing an existing panel, resulting in significant cost savings for the user and increased electrical energy available to the power grid. The invention further discloses installation of a back feed circuit breaker into an existing main panel and main circuit breaker thus, eliminating the need of a home owner to completely reinstall a new electrical system in order to install alternative energy sources such as for example, solar panels and the like.

摘要： A startup control method of controlling startup of a PV PCS 150 configured to perform interconnected operation in which a PV 100 is interconnected to a grid 10 to supply power to a load 400: supplies power from independent operation output of the PV PCS 150 to a storage PCS 250 by an independent operation that does not interconnect the PV 100 to the grid 10 before starting the interconnected operation; measures the output power amount of the PV 100 or the PV PCS 150 when the power is supplied to the storage PCS 250; and stops the independent operation to start the interconnected operation when the measured output power amount is larger than a predetermined amount.

摘要： For each of consumers, a connection control apparatus is provided that includes an opening/closing device capable of connecting or disconnecting an electric power system and a consumer, that, when a power outage occurs in the electric power system, disconnects the electric power system and the consumer from each other by the opening/closing device at a command from an outage management apparatus or the like, and that connects the electric power system and the consumer to each other by the opening/closing device upon receiving a command from the outage management apparatus or the like at the time of restoration from the power outage. A power supply control apparatus supplies electric power from energy provision equipment to electrical appliances during a power outage in the electric power system.

摘要： A utility network powered by a power source has a plurality of substations enabled to power electrical equipment in a participant site. At least one substation is disconnected from the utility network and is to be reconnected via a substation with a power constraint. A processor determines how much power should be shed in a participant site of the substation with the power constraint to allow reconnection of the substation that is disconnected. The processor initiates a Demand Response signal to power consuming equipment in the participant site of the substation with the power constraint to shed power. After shedding power based on the Demand Response signal, the substation that was disconnected is connected to the utility network by closing a switch.

摘要： A system and method of determining priorities for restoration of power in a power distribution system includes collecting customer prioritization data for a set of customers. An inconvenience factor is determined from the customer prioritization data for each customer. A zone restoration factor is then determined from the inconvenience factor for each customer. The inconvenience factor takes into account the estimated outage time, the customer's back-up time, the willingness of the customer to use back-up devices, and customer's priority for the estimated outage time.

摘要： The present invention belongs to electric power engineering field, relates to a method for obtaining a set of symmetric power transfer coefficients under simultaneous change of sources and loads in AC power networks, which comprises the steps of: firstly establishing a linear function of a lossy branch transferred power in terms of buses voltage angles according to a nonlinear function of a branch transferred power, parameters and operation features of the AC power network; then establishing symmetric linear functions of buses injection powers of power sources and loads in terms of buses voltage angles by combining the linear function of the lossy branch transferred power in terms of buses voltage angles and buses injection powers of power sources and loads, in turn establishing symmetric linear functions of buses voltage angles in terms of buses injection powers of power sources and loads; and finally obtaining the symmetric power transfer coefficients from buses injection powers of power sources and loads to the lossy branch transferred power under simultaneous change of sources and loads by using the linear functions just mentioned above. The obtained set of symmetric power transfer coefficients is unique, follows electric circuit laws, is applicable for the practical situations that power sources and loads change at the same time and transmission losses need considering in the AC power network, and truly reflects the substantive characteristics of the power transfer from bus injection powers to branch transferred powers.
