“…The research presented in [8] presents an algorithm for Volt/VAr control in distribution networks with DG. Simulations have been performed in order to reveal that by proper placement of DG units and using appropriate controller for them, it is possible to have much better control for Volt/VAr in distribution networks with decreasing the system losses in the network.…”

“…The injections of power by the distributed generators may change the magnitude and even the direction of the power flow in the network. This has several implications for the operation and planning of the network and has several technical and economic consequences [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17]. In this framework it is clear that DG units affect the network losses, which are defined as the difference between the energy sent out from the generating stations and the energy metered at the customer premises.…”

Distributed generation (DG) is predicted to play an increasing role in the electric power system of the near future. There are different types of DG units from the constructional and technological points of view, which have a different influence on the distribution network. The impact of DG on the network is considered, with a more extensive discussion on the influence of DG on the network losses. The calculation of these network losses is applied in several optimisation programs to quantify an optimal size and location of the DG unit. In these programs the power quality can be taken into account but harmonic losses are rarely considered, although it is known that several DG topologies can have a negative influence on the total harmonic distortion and thus on the harmonic losses. Therefore, this paper will investigate the influence of converter-connected DG units on fundamental and harmonic losses in the distribution network.

“…In many wind farms, the wind measure tower has not been installed, and many real-time data have no access to the EMS system, including wind speed, active power, reactive power, unit operations and power projections. As mentioned in papers by Dresden J and Belmans R (2006), Niknam T et al (2008), Wiik J et al (2002), and Chun-Lung Chen (2008), due to lack of effective technical means to support, some control methods such as peak shaving, frequency and voltage regulation, and real-time planning can not keep up with the development of wind power. Furthermore, wind power output is not included in AGC and AVC closed-loop system.…”

Abstract:The paper introduces the current planning integration situation of the wind power in Northwest Grid of China. The large-scale wind power integration, characterized by concentrated and high voltage level interconnection, makes appreciable effects on power system in stability control, frequency control, load tracking and voltage control. In this situation, the paper studies new requirements of power generation scheduling, dispatch, operation management, power market modelling, grid-connecting operation management, ancillary service management and so on. Finally, the paper introduces the solutions and strategies such as to strengthen the 750 kV grid construction, increase power export of the region, develop a Wind EMS, improve wind power forecasting, explore combined dispatching of wind power and other power plants, and introduce new power market mechanisms.

It is expected that increasing amounts of distributed generation (DG) will be connected to the power system in the future. Advances in technology, deregulation in the market to end the monopoly of the vertically integrated power utilities, alternative energy sources that are becoming more cost effective are encouraging the growth of this new technology. Although there are many advantages, there are many issues to be considered for the interconnection of DG's, like the sizing and siting of the DG. Since it is necessary that the voltages be within a specified limit, this problem of the siting and sizing of the DG has taken top priority as they affect the voltages and operations of the distribution power system. This thesis discusses a procedure for evaluating the impact of the site, size of the DG and also a change in the loading conditions of the system before and after the reconfiguration of the system due to the fault. Many feasible combinations of the size and site of a DG on the IEEE 13 and IEEE 37 node distribution feeder are analyzed, which resulted in large number of data from the load flow. The results and trends are presented. DEDICATION
