“…On the contrary, when the system load is close to the maximum limit, the slight change of the load will lead to the violent fluctuation of the system node voltage. At this time, when the load parameter is still selected as a continuous parameter, it will cause the divergence of the algorithm [18]. In the local parameterization method, continuous parameters need to be re selected at each step of the continuous power flow solution process.…”

As a beneficial supplement to centralized power generation(PG), distributed PG has attracted more and more attention in the world because of its many advantages, such as safety and reliability, low pollution, energy saving and economy, flexible installation location and so on. At present, many scholars at home and abroad have analyzed and studied the power flow algorithm of distribution network with distributed generation(DG) from different angles, and have made some achievements. In this paper, Three phase power flow calculation(TPPFC) of weak loop distribution network(LDN) with multiple distributed generators is analyzed and studied. The influence of human DG on power flow of distribution network and the modeling of various DG and load are analyzed; The three-phase power flow(TPPF) algorithm is discussed. Finally, through the simulation experiment of the TPPFC of the weak LDN with multiple distributed generators, the application of distributed generators to the distribution system(DS) is discussed. The simulation calculation of the IEEE-14 node DS and the ieee-33 node DS with distributed generators is accurate and fast.

Local voltage controllers (LVCs) are important components of a modern distribution system for regulating the voltage within permissible limits. This manuscript presents a sensitivity-based three-phase weather-dependent power flow algorithm for distribution networks with LVCs. More specifically, the proposed algorithm has four distinct characteristics: (a) it considers the three-phase unbalanced nature of distribution systems, (b) the operating state of LVCs is calculated using sensitivity parameters having accelerated convergence, (c) it considers the precise switching sequence of LVCs based on their reaction time delays, and (d) the nonlinear influence of weather variations in the power flow is also taken into consideration. Simulations and validation results presented indicate that the proposed approach outperforms other existing algorithms with respect to the accuracy and speed of convergence, thus making it a promising power flow tool for accurate distribution system analysis.

“…The decision-making department can make corresponding planning and adjustment based on these data. With the advancement of electric power reform and the large number of DGS entering the network, the PL in the system will become more and more difficult to determine [15]. This makes probabilistic PL calculation more and more important.…”

In recent years, distributed generation(DG) has been widely introduced into energy systems. It can not only solve the problem of insufficient security and stability of large-scale energy grid, improve system reliability, but also reduce construction and operation costs and reduce environmental pollution. However, wind power generation, solar power generation and other power generation methods that rely on natural conditions will produce random changes in output, resulting in the system voltage exceeding the limit. On this basis, this paper studies and analyzes the stochastic power flow(PL) calculation of DG and distribution system(DS). A stochastic PL algorithm is proposed. The experimental results show that the stochastic PL calculation of DG and DS is very important to improve the quality of power supply.
