This paper considers the uncertain factors under electricity market, calculates the probabilistic distribution of the Locational Marginal Price (LMP) based on the Point Estimate Method (PEM) 2n+1 scheme. What is more, the correlated loads are considered. The method has higher efficiency than Monte Carlo Simulation (MCS), and the procedure of linearizing the power flow equation in analytical method...
The power grid containing wind farms is analyzed by AC probabilistic load flow. By using the method of the combination concept of Cumulants and Gram-Charlier series expansion theory, the DC probabilistic model is extended into AC probabilistic model, in which a three-parameter Weibull distribution is adopted to describe the random variation of wind speed, meanwhile the asynchronous wind turbine generator...
An AC probabilistic load flow analysis considering the fluctuation of loads, the unscheduled unit outages and random branch outages is proposed. Then it is applied to analyze the power system's static state security. By using the sensitivity matrix and taking the random branch outages as the 0-1 distribution of incremental power injections at each end of the branch, the probabilistic distribution...
This paper establishes probabilistic model, after finishing the calculation of TTC, it uses the method that combines the concept of cumulant and Gram-Charlier expansion theory to calculate probabilistic load flow(PLF).It also analyzes the probability density function(PDF) and immits a new concept-probabilistic Margin(PM),which can make a new system limit for uncertain factor in system. In the end...
