چکیده
In the medium voltage direct current (MVDC) transmission system, a small number of MMC sub modules will reduce power quality. this paper, based on research background Photovoltaic Medium Voltage Direct Current (PV-MVDC) Hybrid Modulation Strategy Decoupled Double Synchronous Reference Frame (DDSRF) control strategy is proposed. The dual arm complementary hybrid modulation combining nearest-level-SPWM (NL-SPWM) can keep SMs in ON state constant. Then, corresponding sharing algorithm module (SM) introduced. Through theoretical calculation, be found to stabilize DC and harmonic content. A 32-level system has been developed verity that proposed its SM have advantages restraining circulating maintaining capacitor balance.

A Genetic-Fuzzy Control Strategy for Parallel Hybrid Electric Vehicle
Hybrid Electric Vehicles (HEVs) are driven by two energy convertors, i.e., an Internal Combustion (IC) engine and an electric machine. To make powertrain of HEV as efficient as possible, proper management of the energy elements is essential. This task is completed by HEV controller, which splits power between the IC engine and Electric Motor (EM). In this paper, a Genetic-Fuzzy control strategy...
متن کاملA Novel Hybrid Droop-Isochronous Control Strategy for Microgrid Management
The droop control strategy is the most common approach for microgrids control but its application is limited due to frequency deviation following a load change. Complementary control strategy has then been proposed to solve the problem using a communication network. However, under this strategy, regular loads profile produces a continuous change of output power of all distributed generators (DG...
متن کاملAn Improved Modulation Strategy for a Hybrid Multilevel Inverter
Multilevel cascaded and hybrid inverter systems conventionally use three level bipolar PWM for each individual inverter, with their carriers phase shifted to achieve maximum harmonic cancellation within each phase leg. This has been shown to give a harmonic performance equivalent to APOD modulation of a NPC multilevel inverter, when the switching frequencies are scaled to achieve the same numbe...

متن کاملLearning a Strategy for Whole-Arm Grasping
Traditionally, robot grasping has been approached in two separate phases: first, finding contact positions that yield optimal grasps and, then, moving the robot hand to these positions. This approach works well when the object’s location is known exactly and the robot’s control is perfect. However, in the presence of uncertainty, this approach often leads to failure, usually because the robot’s...
