Under partial shading conditions (PSCs), photovoltaic (PV) generation systems exhibit multiple local and a single global maximum power point. Consequently, point tracking (GMPPT) is required to improve the performance of PV in such scenarios. This paper comparatively studies evaluates modern heuristic-optimization-based GMPPT techniques. Monte Carlo method used statistically analyze different m...

This Paper presents Maximum Power Point Tracking (MPPT) of Photovoltaic Array under partial shading condition. The power available at the output of photovoltaic cells keeps changing with solar insolation and ambient temperature because photovoltaic cells exhibit a nonlinear current voltage characteristic. A good number of publications report on different MPPT techniques for PV system most of th...

In this paper, a robust Maximum Power Point Tracking (MPPT) for PV array has been proposed using sliding mode control by defining a new formulation for sliding surface which is based on increment conductance (INC) method. The stability and robustness of the proposed controller are investigated to load variations and environment changes. Three different types of DC-DC converter are used in Maxim...

in recent year's renewable energy sources have become a useful alternative for the power generation. the power of photovoltaic is nonlinear function of its voltage and current. it is necessary to maintain the operation point of photovoltaic in order to get the maximum power point (mpp) in various solar intensity. fuzzy logic controller has advantage in handling non-linear system. maximum power ...

This article contends that legitimacy in the exercise of power comes from the consent of those subject to it. In global health, this implies that the participation of poor country citizens is required for the legitimacy of major actors and institutions. But a review of institutions and processes suggests that this participation is limited or absent. Particularly because of the complex political...

gorik ooms recently made a strong case for considering the centrality of normative premises to analyzing and understanding the underappreciated importance of the nexus of politics, power and process in global health. this critical commentary raises serious questions for the practice and study of global health and global health governance. first and foremost, this commentary underlines the impor...
