This paper presents a photovoltaic (PV) generator along with a battery energy storage system connected in series with a three-phase grid. The objective of the proposed system is to provide uninterruptable compensation to the series-connected grid and non-linear load during strong sunlight as well as at night or in cloudy conditions. The interface between the grid and the PV is carried out through a voltage source converter (VSC), eliminating both the current and voltage harmonics and compensating the reactive power. The DC voltage control of the DC bus capacitor is employed in order to maintain unity power factor operation of the system, irrespective of changes in solar radiation level or due to change in load. Another control scheme is implemented to charge and discharge the connected battery whenever the sun goes out, to meet the DC bus voltage requirement of the VSC through a bidirectional DC-DC converter.

The Impact

The intermittent behaviour of renewable energy generation has become an essential issue for power deficiency in the distribution network. The high penetration of wind and solar became the primary task for the optimal size of energy storage to support the power mismatch. In the present work, the impact of the energy storage device with distribution generation (DGs) have been determined in a renewable integrated distribution system for power loss minimization. The main contribution of this paper is: (i) optimal location of DGs and battery are obtained by solving single and multi-objective functions. (ii) Determination of DG and battery size for minimization of power loss and system cost. (iii) Impact of battery energy storage device on loss profile and total cost of the system. The impact of day load variation has been considered in the study. The results have been obtained for IEEE-33 bus test system using a hybrid GAMS and particle swarm optimization (PSO) algorithm. The power loss is reduced to 47.60% with single DG and battery energy storage (BES). In addition, the power loss is reduced to 59.285% with two DGs and BES. The simulation results of the test system have been compared with other existing results.
