“…Though they have drawbacks as mentioned in the introduction, yet they are the simplest to design and the least expensive to implement for low and medium power applications. Different types of passive filters have been introduced and various designing techniques have been proposed in the literature like single tuned filter, first order high-pass filter, second order highpass filter etc [7], [14], [15].

“…Z load V = j L + in 1+ j Z C load (13) Using (12) and (13), (11) can be rewritten as 1 G( j ) = L 2 1+ LC( j ) + j Z load (14) where Z load is the impedance of the load connected to the standalone PV generation system. The L value for the LC filter is chosen using (15) where, f sw is the switching frequency of the inverter switches.…”

“…The L value for the LC filter is chosen using (15) where, f sw is the switching frequency of the inverter switches. The maximum ripple current ripple , is assumed to be 5% of the rated current [14]. V 1 in L = 8 f ripple sw (15) The inductance L should be limited to a minimum possible value owing to its large volume.…”

“…The capacitor in the LC filter attenuates the harmonics by providing a low resistance path to ground. The capacitor value is chosen based on the reactive power absorbed by the LC filter [14]. The value of C should be such that it provides a good power factor at fundamental frequency and it is reasonably kept low to avoid large currents that may damage the switching devices.…”

Harmonic reduction in inverters fed from a standalone PV system is currently becoming important in medium power applications. This paper focuses on the design and analysis of various passive filters for power quality improvement in standalone PV systems. Different passive filters are designed and analysed to reduce the total harmonic distortion of the proposed system. The passive filters include LC, LCL and LLCC filter topologies. A comparison study of the total harmonic distortion reduction with the above filters is done. Further, the paper attempts to show that the use of LLCC filter with a standalone PV system can highly improve the power quality of the system. Results are verified using simulations in MATLAB-SIMULINK environment.

In some rural areas in the northwest of China, people are suffering from not only the voltage drop due to long distance transmission but also the power outages due to remoteness and poorly maintained grid. In recent few years, the price of solar energy has been reduced drastically every year in China due to the government policy on renewable energy. In the near future, isolated hybrid power systems for home use could be affordable and used by residences in these rural areas. Thus, it is necessary to design a hybrid power system based on local load and weather condition to check system feasibility and expected performance. It includes load simulation, system sizing, and dynamic system modeling and simulation. This paper firstly introduces current development of renewable energy in China and then goes through the sizing, modeling, and simulation of the system design for a typical remote home in China and finally discusses the system's availability based on the simulation results. In this paper, the NASA website is the source for weather data, and BEopt is used to generate load data. During system modeling, the MPPT algorithm is much simpler designed than the complex incremental method. A soft starter is adopted with the diesel generator for stability. The charge controller of the battery storage provides external command to the MPPT and diesel PID controller to prevent the battery storage from overcharging. The rms value of the fundamental load voltage is used in the voltage control loop of the inverter.
