Description: Production of energy in centralized power plants
and transmitted via transmission lines to the customers is
always with high power losses. Distributed generation
(DG) especially renewable energy resources (RES) and
energy storage systems (ESS) through distributed system
are very cost saving and sometimes inevitable. If these
small DGs want to connect to power system and participate
in energy market directly, both distribution and energy
market would have many problems with control such a high amount of information and small supplies of DGs. Application of virtual power plant (VPP) as an aggregation of some DGs with own local energy management system and some fix and variable loads is a suitable solution for DGs and networks problems.

Description: In order to minimize power losses caused by high current and improve the voltage profile in the network distribution, the introduction of dispersed generations also called productions decentralized in distribution network (DG) plays an important role. The installation of DGs directly affects the power requested or purchased. The sizing and placement of DGs in the system must be optimal because a wrong choice has a negative impact on the system behavior. To solve this combinatorial problem, an algorithm known as Firefly algorithm is proposed in this paper. This is a meta-heuristic algorithm inspired by the behavior of fireflies flashing. The main objective of firefly flash is to act as a signaling system to attract other fireflies. Networks tested IEEE69-bus and IEEE33-bus are used to evaluate the effectiveness of this method. The results are compared with those obtained by genetic algorithm (GA) to IEEE69-bus, and Shuffled frog leaping algorithm (SFLA) for IEEE 33-bus.

Description: With the increasing penetration of renewable energies as distributed generation
(DG) in smart grid scheme, technical problems arise in both distribution and transmission
system level. Undesirable voltage is the main problem for connection of
DGs in distribution systems while excessive reactive power demand transmission
system is the major concern for Transmission System Operators.
The low power generation capacity of DER (Distributed Energy Resources) has
motivated the need for integration of different types of DERs and loads in the form
of micro-grid to enhance the power generation capacity, reliability and marketability
of dispersed type of micro-sources [12, 13]. Current harmonics and Reactive power
consumption are the two power quality issues that are addressed in this thesis-With the increasing penetration of renewable energies as distributed generation

Description: 考虑分布式电源的配电网电压控制新方法。针对含分布式电源的配电网电压越限问题，提出了一种基于灵敏度分析进行综合调节分布式电源出力和投切电容器组的电压控制新方法。当配电网出现节点电压越限，通过计算各个节点的注入无功功率对电压的灵敏度，以系统节点电压偏移最小为目标函数，采用和声算法，综合确定调节分布式电源出力大小和投切电容器组大小，并对分布式电源是否参与电压控制的控制效果和是否按电压灵敏度调节电压的控制效果进行了比较。-New Method of Voltage Control Considering Distribution Network Containing Distributed Generation. Considering out of limit voltage in distribution network containing distributed generation(DG)，a new method of voltage control is proposed，which is based on sensitivity analysis and consists of comprehensive regulations of outputs of DGs and switching capacitor groups．When out of limit voltage appears，the sensitivity of voltages in each node caused by input reactive power is worked out，with minimum shifts of nodes in system selected to be an objective function and harmony search algorithm adopted as calculating method，then the magnitude of outputs of sources and switching groups is determined comprehensively．Also the performances of voltage control with and without DGs and regulations by voltage sensitivity are compared．This paper deduced sensitivity matrix in cartesian coordinates，and employed IEEE-33 bus system to verify the control strategy，and verified its correctness and effectiveness
