Distribution Network Operation Optimization Method Including Agricultural Power Irrigation

Résumé fourni par la source

Agricultural irrigation load is a large proportion of agricultural production load. Agricultural irrigation load is a typical power flexible load, which can be adjusted over a long time scale. By using the characteristics of agricultural irrigation load, the agricultural irrigation load is added to the power grid regulation to participate in the grid interaction and cooperate with renewable energy to achieve the purpose of optimizing the power quality. Firstly, this paper analyzes the power characteristic of electric drainage and irrigation, turns the operation optimization problem of pumping station into a linear problem, calculates the optimal operation strategy of pumping station under time-of-use electricity price, and substitutes the optimized load of electric drainage and irrigation into the distribution network. Then, we analyze the adverse effects of electric drainage and irrigation load on distribution network. The optimization strategy of distribution network operation is proposed by using particle swarm optimization algorithm. Finally, an IEEE 33 node standard example is used to verify the effectiveness of the proposed optimization method.
