From the point of economic operation and dispatch strategy whole power system, cost requirement changes ancillary service are analyzed with wind integration in this paper. And paper proceeds as follow: first, current situation system accommodation China is introduced. then based on overseas experience reference model for increased established, a provincial data an example, caused by analyzed, potential influence different strategies expatiated. Finally countermeasures improved improving...
With the rise of micro-grid, renewable energy such as wind and solar power is introduced to electric grid, which has random intermittent characteristics, thus having great impact on safety stability for grid. This paper deeply analyzes situation where multiple micro-grids are connected grid establishes a scheme joint scheduling model distribution network, considers network loss, load fluctuation operation economy. Then combined bi-level optimization algorithm solve this model. The simulation...
High penetration of electric vehicles has brought huge impact on the safe and stable operation power grid. How to effectively improve comprehensive utilization rate vehicle charging discharging become most important problem for grid operation. In this paper, we establish centralized station model which takes minimal real loss as its objective bring variance optimization function. Using IEEE 30-bus system simulation system, paper uses genetic algorithm find best solution above model. The...
Renewable energy developed rapidly in China of recent years, and its installed capacity is just less than the coal power hydro power. It changing from supplementary source to alternative step by step, expected play a leading role future development. In order realize high proportion development target promote sustainable development, this paper states current technology status renewable represented wind solar power, analyzes problems it faces, finally put forward key trend future.
According to the impact of wind power prediction uncertainty on system reserve capacity, idea scenario is introduced stochastic programming model. The method used simulate model generation, load and conventional units. scenario-reduction methodology combined reduce large set a simpler one, then probability statistics these scenarios given in order obtain density difference, expected energy not supplied (EENS) waste risk (EWWR) are presented. capacity determined by two aspects, which...
An optimal assignment algorithm of emergency power supply considering V2G is proposed with a necessary concern for its effect on society. Firstly, the comprehensive index weight coefficients are according to priority. Next, this paper establishes network minimum total cost objective function based constraints such as time and capacity limit, using symmetric triangular fuzzy numbers simulate uncertainties in logistics condition that ensuring normal work EV next day which used search best...
