Genetic algorithm (GA) is an important method of multi-objective optimization. The method is introduced that using GA optimizes PPF parameters in this thesis. Distributed generation (DG) is a hot spot nowadays, but the harmonic pollution isn't ignored when DG is connected with the power grid through power convertors. First discuss several harmonic suppression methods have been adopted in practice, such as increasing the pulse number of convertor, using pulse width modulation (PWM) convertor, passive power filter (PPF) equipment, active power filter (APF) equipment and so on, among these Hybrid type combining PPF and APF is the most economical and effective method, so Hybrid type equipment is applied to suppress harmonics that are brought by gridconnected DG. From three respects of the cost, the DG penetration power and the total harmonic distortion (THD), using GA optimizes the PPF parameters, namely R, L, C, optimization results make the PPF cost is the most economical, the DG penetration power is the largest and the THD is the smallest, simulation shows this method is effective.

“…Therefore, the vector controller is designed by considering the equivalent series connection of the LC-and LCL-filter inductors, simplifying the control problem to that of a first-order system. This would result in imprecise description of an LCor LCL-GCC system and cause potential oscillatory and/or unstable dynamic behavior [6,10].…”

“…Therefore, a damping strategy usually accompanied the vector controller for LC-and LCL-filter GCCs mainly in two main categories: (1) passive damping [11,12] and (2) active damping [6,10,[13][14][15][16][17][18]. Passive damping is mainly based on adding resistive elements to an LC or LCL filter.…”

“…Active damping was first developed to stabilize voltage sourced converters with input filters in [17] and was realized as a "virtual resistor" principle in [18]. The main advantage is it avoids the power dissipation problem of passive damping techniques.…”

This paper addresses stability problems of power systems with actively controlled loads that exhibit constant-power behavior. Instability occurs in such systems due to the negative incremental resistance of the constant-power loads (CPL). Existing approaches to stabilizing such systems require modification of the source and/or the load control characteristics, or isolating the CPL from the rest of the system by additional active devices, which are difficult to implement and often conflict with other system requirements such as control bandwidth, size, weight, and cost. In this work, we propose passive damping as a general method to stabilize power systems with CPL. Using a representative system model consisting of a voltage source, an LC filter, and an ideal CPL, we demonstrate that a CPL system can always be stabilized by a simple passive damping circuit added to one of the filter elements, no matter how the original system behaves. Three different damping methods are considered and for each analytical models are developed to define their parameters required for stabilizing the system. The different damping methods are also compared in terms of their stabilization capabilities and impact on other system performances such as filter attenuation. Time-and frequency-domain measurements from an experimental system are presented to validate the proposed methods.
