ActiveCN107666155ASafe and stable operationContinuous and stable powerSingle network parallel feeding arrangementsPower oscillations reduction/preventionNew energyLaws of thermodynamics
The invention provides a Markov model-based multi-energy complementary system random stability analysis method. In order to reasonably describe the changing condition of the illumination and the windspeed, existing illumination data, wind speed data and the like are subjected to clustering analysis, and then the center point of each cluster is obtained. The center point of each cluster is adoptedas one Markov state. A transfer rate matrix between all states is obtained through Bayesian reasoning. According to the Kirchhoff voltage and current law, a Markov state space model is built. On theabove basis, a random Lyapunov function is constructed for carrying out the random stability analysis. Moreover, though detecting the current value of a grid connection point, a current controller isdesigned to carry out the in-situ reduction of an adjustable load. According to the fluctuation condition of the new energy power generation, the consumption amount of the load is adjusted. Therefore,the power transmitted to the power grid is guaranteed to be continuous and stable. Finally, the simulation operator test is established and then the effectiveness and the practicability of the methodare verified.

According to the device, the structure is optimized, air suction and outflow resistance is reduced, therefore, the total air volume of a gasoline engine at the same rotating speed is higher than the total air volume of a common impeller, the engine oil cooling effect is obviously improved, power is higher, and power is continuous and stable.

Stochastic Stability Analysis Method of Multi-energy Complementary System Based on Markov Model

The invention provides a Markov model-based multi-energy complementary system random stability analysis method. In order to reasonably describe the changing condition of the illumination and the windspeed, existing illumination data, wind speed data and the like are subjected to clustering analysis, and then the center point of each cluster is obtained. The center point of each cluster is adoptedas one Markov state. A transfer rate matrix between all states is obtained through Bayesian reasoning. According to the Kirchhoff voltage and current law, a Markov state space model is built. On theabove basis, a random Lyapunov function is constructed for carrying out the random stability analysis. Moreover, though detecting the current value of a grid connection point, a current controller isdesigned to carry out the in-situ reduction of an adjustable load. According to the fluctuation condition of the new energy power generation, the consumption amount of the load is adjusted. Therefore,the power transmitted to the power grid is guaranteed to be continuous and stable. Finally, the simulation operator test is established and then the effectiveness and the practicability of the methodare verified.
