for power flow management of a multi array PV battery based system connected transformer coupled bi directional DC-DC converter is introduced. The proposed system are expects to fulfill the heap request deal with the power flow from various source inject surplus power in to the grid. Bi-directional buck-bust converter is used to control power from photovoltaic along with battery charging – discharging control. The proposed system aims to satisfy the load demand, manage the power flow from multiple sources, inject surplus power into the grid and charge the battery from grid as and when required. The proposed system number of steps is less to convert solar dc power to high quality ac power, and decrease power losses compared to existing grid-connected hybrid systems. In these power system are connected same source (two PV source) and improves the voltage regulation, efficiency and reliability of the system.
2. Literature survey Shafinaz A. Lopa et al.(2016) - It contains the theoretical derivations and parameters equations with design and examples. We have analyzed the equation of a buck; boost and buck boost converters and proposed the design components and simulation of these converters. We have achieved performance parameter equations for these three regulators. It was completed the design and investigation of these three converters through mathematical examples and have generated the circuits for simulating buck, boost and buck boost converters. And also have attained different output voltage curve with the change of input parameters. The output graphs for all the converters are well fitted.

1. INTRODUCTION
B. Venkata Seshu Babu et al. (2017) – In this paper A hybrid wind/PV system for supplying an isolated small connectivity system with electrical energy is digitally simulated and presented. A control strategy for power flow management of a grid-connected hybrid photovoltaic (PV)–wind battery based system with an efficient multiinput bidirectional dc–dc converter is presented. A converter is used to harness power from wind, while a bidirectional buck–boost converter is used to harness power from PV along with battery charging/discharging control. The proposed converter architecture has reduced number of power conversion stages with less component count and reduced losses compared with existing gridconnected hybrid systems. This improves the efficiency and the reliability of the system. The proposed controllers are coordinated dynamic error driven PI regulators to control the interface converters.
Renewable energy generation is eco friendly option for power generation. The proposed configuration can not only boost the usually low photovoltaic (PV) array voltage, but can also convert the solar dc power into high quality of ac power for feeding into the connected grid, while tracking the maximum power (MPP) from the PV array. Writing on PV related themes covers procedures for most extreme force point following (MPPT), late surveyed for instance in, power quality improve and exact regulate in electronic circuit geographies for DC-DC converters, DCAC inverters, and single stage power converters [1] Photovoltaic energy is expecting progressively significant as an environmentally friendly power source due for its unmistakable potential benefits, like basic arrangement, simple assignment, liberated from contamination for the few decades ago using solar energy for power generating houses was the unbelievable task but quick transformations form the few years for developing the solar power having the energy supply is implemented[2]. Today the solar PV systems are widely used for extracting the energy for using for household purpose commonly [3]. The power from solar PV is used commonly for purpose like right powering from all homes.
