This paper focuses on the application of modular multilevel matrix converter (M3C) in fractional frequency offshore wind power system (FFOWPS). M3C is one of the direct ac-to-ac power converters capable of bidirectional power flow. It has many advantages compared with traditional cycloconverter, so it is more competitive and promising to be used in FFOWPS. This paper constructs an equivalent circuit...
Fractional frequency transmission system (FFTS) is utilized to transmit large-scale and remote wind power. By adopting a lower frequency (50/3 Hz), FFTS could reduce the electric distance of transmission lines, thus lowering the transmission loss. In order to analyze the interconnected system of FFTS and main grid, the power flow calculation should be conducted. This paper introduces a new method...
Wind power producers face risks on both power generation and market price in electricity markets. This paper proposes the block futures contracts as a financial approach to risk management for wind power trading, where futures contracts are signed with different hedge ratios for different power blocks. The independent transaction on futures contracts for each power block leads to a much better hedging...
Wind power grid integration via fractional frequency transmission system is an effective approach to large-scale longdistance transmission of wind power, which could solve the problem of limited transmission distance of industrial frequency AC cable and save the investment cost of offshore platforms when applied to offshore wind power. Generator-side converter could also achieve the maximum wind power...
