| Abstract: |
| In order to improve the frequency regulation capability of offshore oil and gas platform power grid containing wind power, a coordinated frequency auxiliary control method of wind farm and gas turbine unit on the offshore oil and gas platform is proposed based on the multi-agent consistency theory, inside the wind farm a double-fed induction generator is taking as a unit. The offshore isolated power grid is regarded as a multi-agent system, the wind farm and the gas turbine unit on the offshore oil and gas platform are regarded as agents. Based on the topological information of the offshore power network, the communication network of multi-agent system is constructed to realize the information interaction among agents. The multi-agent models of frequency auxiliary control for wind farm and gas turbine unit on offshore oil and gas platform are established respectively. The controller structure is given based on the multi-agent consistency algorithm, and the frequency coordination control between wind farm agents and gas turbine unit agents is realized based on the multi-agent communication network. The parameters of the controller are optimized by linear quadratic optimal control. The effectiveness of the proposed control method is verified by a simulation example. The results show that the proposed coordinated frequency auxiliary control method can effectively improve the frequency regulation capability of the system and suppress frequency fluctuations. |
