1.Intelligent Optimized Voltage Control for Hybrid Off-Grid Power Systems
Hybrid off-grid power systems with different renewable and non-renewable energy sources, such as wind, photovoltaics, and diesel generation, have a wide application scope in regions where grid extension is not possible. To supply quality power, hybrid off-grid power systems need proper reactive power management to deal with randomly changing load and supply. In particular, to realize dependable and quality power supply, hybrid off-grid power systems require suitable and efficient control techniques. A properly tuned controller of reactive power sources is crucial to maintain a prescribed voltage profile.
2. PID Controller Tuning using ACO Algorithm for AVR Systems
This paper features an effective technique to device the parameters of PID controllers for utilization together with an Automatic Voltage Regulator System (AVR). The quintessential goal is to acquire a good load disturbance response by minimizing the performance index/(Integral time square error). Simultaneously, the transient response is assured by limiting maximum overshoot, settling time and rise time of the step response to minimal values. For achieving these goals, optimum and quick tuning of the parameters (Kp, Ki, and Kd) is essential.
3. Optimal controllers design for voltage control in off-grid hybrid power system
Generally, for remote places extension of grid is uneconomical and difficult. Off-grid hybrid power systems (OGHPS) has renewable energy sources integrated with conventional sources. OGHPS is very significant as it is the only source of electric supply for remote areas. OGHPS under study has Induction generator (IG) for wind power generation, Photo-Voltaic source with inverter, Synchronous generator (SG) for Diesel Engine (DE) and load.Over-rated PV-inverter has capacity to supply reactive power. SG of DE has Automatic voltage regulator for excitation control to regulate terminal voltage. Load and IG demands reactive power, causes reactive power
imbalance hence voltage fluctuations in OGHPS.
4. Optimized voltage and frequency control in off-grid Power System
This paper presents optimized control voltage and frequency of off-grid power system (OPS) . The off-grid power system considered in this is having small isolated load supplied by power generation from of wind , PV and Diesel .wind energy converting system (WECS) consist of fixed speed squirrel cage Induction generator (SCIG) , Photovoltaic system(PV) is connected through inverter. The other source in the OPS is diesel-genset equipped with governor and synchronous generator (SG) with automatic voltage regulator (AVR). Any variation load power causes frequency and voltage fluctuations.
