Wind Farm Energy Storage Capacity Of The Battery Optimization

With the rapid development of the world economy, global demand for electricity continues to grow. However, due to the impact of oil, coal and other primary energy environment and climate, making wind power and other clean energy being widely developed and used. However, wind power generation is random, volatile and difficult to predict, so that the large-scale wind power grid safe operation and stable power system brings a range of effects. Meanwhile, the installed capacity of wind power also has expanded each year, so the impact of wind power in the electricity system more attention from people.System wind power generation gives effect buffering energy reserves and the balance of the storage device of energy is introduced into the system of production of wind energy, which can be stabilized effectively fluctuations in its power to reduce the negative effects of energy wind energy network system, increasing energy conservation technology network stability and functioning capacity of wind power consumptive power system security. At various technologies of energy storage, battery flow have a long life cycle, simple structure, low cost,power and capacity independently of each other, etc., they are now widely used in storage systems energy. In addition, the density super capacitor power, high efficiency power conversion, but expensive, and so the combination of the composition of course mixed system of energy storage battery, allowed play to the strengths of their own, ideal for use in system wind power energy storage. In this case, we propose optimizing configuration storage capacity from different times wind power level smoothing, wind power generation farm to reach an exit soft and power output of wind farms can participate in the planning existing. It’s main work:(1)Fluctuation characteristics of power generation windmills, and gives the device of energy conservation to stabilize the effects of fluctuations in wind energy related assessment and flow batteries, features super capacitor and mathematical models to optimize the distribution system energy storage capacity It provides a basis for decision making.(2)Creating a diversion and storage power output standard capacity and the cost of wind turbines and construction of energy conservation as a function target of optimism, depending on the window time, get another power output reference, use the clutch particle optimization algorithm for example numerical analysis and optimization calculation, take a different storage capacity must be configured in different time windows. In the current production, in accordance with local planning, select a different time window, choosing wind power and better economy requires a set of configuration parameters such as capacity-optimized battery configuration required nominal flow capacity.(3)Combined storage energy flow batteries and storage super power capacitor characteristics of each hybrid system proposed energy conservation involved in wind farm output to stabilize fluctuations in wind energy output Farm scheme coordinated control is calculated based on the principle filter low-pass flow battery- Ultracapacitor energy storage system hybrid in both power and capacity of their configuration, storage and analysis of energy conservation contrast the only way hybrid technical and economic advantages.
