Abstract

The invention relates to a multi-type power supply capacity long-term planning method considering offshore wind power access. A modeling method of offshore wind farm output is proposed based on the correlation theory. The problem of offshore wind power absorption is introduced into the power planning level. Considering the peaking capacity constraints of multi-type power supplies and the system reliability constraints based on stochastic production simulation, the capacity optimization model of multi-type power supplies is established with the construction and operation economy as the goal, and the particle swarm optimization algorithm is used to solve the problem. The method is simple and practical and has high operability and solves the problem that the traditional planning method only pays attention to economic indicators and does not consider enough the peak shaving capability and reliability of the system. The method can solve the problem of peak shaving difficulties faced by windpower absorption and has great significance to ensure wind power absorption and safe and stable operation of the power grid and provides a feasible scheme for long-term power supply planning in coastal and offshore provinces rich in wind power resources.

Description

technical field [0001] The invention relates to the field of power system expansion planning, in particular to a long-term planning method for multi-type power supply capacity considering the access of offshore wind power. Background technique [0002] In recent years, my country's onshore wind power abandonment has been serious, and the urgent need to solve the problem of wind power consumption has restricted the development of onshore wind power. In contrast, offshore wind power is close to the load, and has the advantages of not occupying land, rich wind resources, and stable operating conditions. With many advantages, it has become a new outlet for the development of the wind power industry. [0003] Unlike conventional hydropower and thermal power, wind power output has obvious randomness and volatility, and often has the characteristics of anti-peak regulation. Large-scale offshore wind power grid integration makes the peak regulation contradiction of the power grid mor...
