Power storage device and control method of distributed power supply system equipped therewith

Abstract: PROBLEM TO BE SOLVED: To surely restrain fluctuations in output to a power system due to a distributed power supply, such as wind power generation and solar power generation by preventing a power storage part from having storage shortage or being kept in a fully charged condition. SOLUTION: This distributed power supply system 10 is provided with a power storage device 1 consisting of the distributed power supply 9, the power storage part 2, a power-regulating part 3, and a control part 4 and is connected to the power system 12. The control part 4 consists of an output detecting part 5, a storage detecting part 6, a target value setting part 7, and a regulating output control part 8. It detects an output P of the distributed power supply 9 and the storage amount of the power storage part 2, presets an output target value P0 for restraining fluctuations in the output to the power system 12 by the distributed power supply 9 according to the storage amount, and controls the power regulating part 3 so that the output to the power system 12 reaches the output target value P0.

Load forecasting for active distribution networks

Abstract: This paper addresses the problem of electric load forecasting for distribution networks with Active Demand (AD), a new concept in smart-grids introduced within the EU project ADDRESS. By changing the typical consumption pattern of the consumers, AD adds a new dimension to the problem of load forecasting, and therefore makes currently available load forecasting techniques no more suitable. A new approach to load forecasting in the presence of AD is therefore proposed. The approach is based on a decomposition of the load into its components, namely the base load (representing different seasonal patterns), and a residual term depending both on stochastic fluctuations and AD effects. The performance of the proposed approach is illustrated through a numerical example. Since data sets including AD are not yet available, in the numerical example AD effects are simulated and added to real measurements representing the aggregated load of about 60 consumers from an Italian LV network.

Day-ahead Generation Scheduling and Operation Simulation Considering Demand Response in Large-capacity Wind Power Integrated Systems

Abstract: The stochastic fluctuations of wind increase the difficulty in operating scheduling in power system.This paper established a generation scheduling model and operation simulation model considering demand response in large-capacity wind power integrated system.In the model reserve cost for wind power was incorporated into objective function and up spinning reserve and down spinning reserve were considered.Load curve was predicted according to user response principle based on consumer psychology and interrupted load acted as part of system reserve.The effectiveness of TOU and IL was integrated into one model on account of coordinating generate and demand side,which could respond to characteristic of negative peaking load shifting intermittency of wind power.The wind energy curtailment and loss of load before and after considering demand side response under varieties of wind power outputs were estimated by Monte Carlo simulation.The relationship between wind power penetration and wind energy curtailment and the one between wind power capacity and loss of load were presented in this paper.The simulation on IEEE 24-bus system indicated this model can decrease the generating cost effectively and increase utilization ratio and levels of capacity usage of wind power.

Optimized load management

Abstract: For optimizing a chronological developing of consumption of electric power by a group of different consumers (2 to 7) with regard to a supply of electric power including electric power from at least one wind or solar power generator (8), a consumption of electric power by the individual consumers (2 to 7) is measured to determine characteristic time curves of the consumption of electric power by the individual consumers (2 to 7); a prognosis of a chronological developing of the supply of electric power from the at least one power generator (8) is made for a future period of time; a plan for apportioning electric power to the individual consumers (2 to 7) within the future period of time is made based on the characteristic time curves of the consumption of electric power by the individual consumers (2 to 7) and adapted to the prognosis; and electric power is apportioned to the individual consumers (2 to 7) according to the plan within the future period of time. Apportioning electric power to the individual consumers (2 to 7) is executed via at least one switchable single connector for a single one of the individual consumers (2 to 7) and/or effected by accessing an interface of a controller (27) of at least one individual consumer (2 to 7).
