“…The first (I) controller belongs to the PV converter by its MPPT controller. Solar cells from the PV systems are nonlinear characteristics and are considered to operate the maximum power point (MPP) under those changes [38]. The most forceful method for better harvesting energy from PV cells is the MPPT technique.…”

In this paper, an intelligent energy management system for the smart home that combines the solar energy as well as the energy from the battery storage devices has been proposed to reduce the dependency on the power grid and make the system to be more economical. The proposed system manages the energy requirement of the smart home by properly rescheduling and arranging the power flow between the energy storage devices, grid power, and the photovoltaics. The power grid can absorb the excess power from the designed system whenever the load requirement is low, and on the other hand, it can supply the power to the load in case of peak demand. Therefore, in the designed system, a user has the flexibility to sell the extra power for the purpose of revenue. A thorough simulation of the system has been carried out, and the results obtained show the effectiveness of the approach in terms of energy management between the different sources.

Due to the bypass diodes, the partially shaded photovoltaic (PV) string exhibits multiple peaks in the P-V curve. And the conventional Maximum Power Point Tracking (MPPT) methods are not capable of tracking the global peak (GP) under partially shaded condition (PSC). In order to track the GP fast and efficiently under uniform irradiance condition (UIC) and PSC, a modified incremental conductance (INC) method is proposed in this paper. This method can not only detect the occurrence of PSC, but also determine if the other peaks need to be tracked under PSC by using the relationship between the minimum current at other peaks and the short circuit current to enhance the tracking speed. In order to improve efficiency, the converter duty cycle will be regulated slightly to ensure that the operating point reaches in the vicinity of GP, after the approximate GP is located. The Matlab simulation results show that the proposed method is faster and more efficient than other methods. It only requires 3 and 11 sampling cycles to locate the GP under UIC and PSC, respectively. Its overall tracking efficiency is increased by 13.61%, 4.28% and 0.42% under UIC, PSC and one-day irradiance profile respectively, compared to the conventional INC method.
