| 摘要: |
| 传统电力系统随机生产模拟方法难以描述新能源发电机组时序特性以及计算与时序特性有关的电力系统运行指标，导致生产模拟的准确性欠佳。提出含风电、光伏、水电、火电、光热及储能的多能源时序性随机生产模拟方法。将系统运行调度策略与随机生产模拟中各类型机组的加载顺序相结合，计及电力系统网架断面约束，充分保证新能源的优先消纳。为保留电力系统时序特性，基于等效电量函数法以每小时作为模拟步长统计模拟期间内的系统运行指标。我国某省实际电力系统随机生产模拟结果验证了所提方法的有效性。 |

| Abstract: |
| The traditional stochastic production simulation methods of power system are difficult to describe the time series characteristics of renewable energy generator units and calculate the operation indexes of power system related to time series characteristics, which results in poor accuracy of production simulation. A multi-energy time series stochastic production simulation method including wind power, photovoltaic, hydropower, thermal power, photothermal and energy storage is proposed. The system operation scheduling strategy and the loading sequence of each type unit in stochastic production simulation are combined, taking the section constraints of power system into account, the priority consumption of renewable energy is fully guaranteed. In order to preserve the time series characteristics of power system, the system operation index during the simulation period is counted based on the equivalent energy function method with per hour as the simulation step. The stochastic production simulation results of an actual power system in a province of China verify the effectiveness of the proposed method. |
