[IEEE 2019 International Conference on Smart Energy Systems and Technologies (SEST) - Porto, Portugal (2019.9.9-2019.9.11)] 2019 International Conference on Smart Energy Systems and Technologies (SEST) - Modular Architecture with Power Optimizers for Photovoltaic Systems
摘要： Solutions that increase ef?ciency in renewable energy are important for environmental sustainability. In this way, dealing with photovoltaic generation a new architecture constituted by power optimizer for photovoltaic systems emerges. Power optimizer is a DC/DC converter, allocated to each one or two photovoltaic modules, that tries to reduce losses in photovoltaic systems, increasing the photovoltaic power generation. Thus, this paper presents the architecture used in a photovoltaic system with power optimizer and a performance simulation for application in a residence and a photovoltaic plant. Thus, it is possible to measure the gain provided by power optimizer in simulated systems. As a result, the application of the photovoltaic system in residence provided better performance than the application in the photovoltaic plant, due to the greater frequency of shading in the photovoltaic modules. Therefore, power optimizer for photovoltaic systems is a solution that can be considered, mainly with the reduction of the cost of power electronics in the future.

Energy Management System for the Photovoltaic Battery Integrated Module
摘要： Given the complementary nature of photovoltaic (PV) generation and energy storage, the combination of a solar panel and a battery pack in one single device is proposed. To realize this concept, the PV Battery Integrated Module (PBIM), it is fundamental to analyze the system architecture and energy management. This paper focuses on selecting a suitable architecture among the different options, while also indicating the control strategy that the converters must follow to ensure appropriate performance. Also, several modes of operation for the complete system are introduced to implement energy management. For the selected DC architecture, two case studies, viz. off-grid and peak-shaving for a grid-tied system, were employed to characterize the response of the model demonstrating its utility to perform maximum power-point tracking, excess solar power curtailment, and battery charging and discharging. The proposed control and system architecture prove to be feasible for a PV Battery Integrated device such as PBIM.
