The electrical system also includes a common AC bus coupled between outputs of the inverters and an electrical power grid. The electrical system also includes local controllers coupled to the inverters and decentralized controllers coupled to the local controllers. The decentralized controllers measure voltages and currents of the electrical power grid and the inverters and generate decentralized control signals for the local control controllers based on the measured voltages and currents.

Abstract

Split-cell and multi-panel photovoltaic backtracking control systems and methods allow for increased total power generation during low sun elevation conditions by shading a percentage of panel modules, thereby allowing for a lower angle of incidence on unshaded modules. The control systems and methods involve determining a sun elevation angle, a traditional backtracking angle, a split-cell or multi-panel backtracking angle, a single-cell or single-panel relative light transmission (RLT) based on the single-cell or single-panel backtracking angle, and a split-cell or multi-panel RLT based on the split-cell or multi-panel backtracking angle. If twice the single-cell or single-panel RLT is greater than the split-cell or multi-panel RLT, the split-cell or multi-panel backtracking angle is used; otherwise, the single-cell or single-panel backtracking angle is used. The control systems and methods may further involve determining a diffuse fraction index (DFI) and, if the DFI is greater than a DFI limit, using a DFI tracking angle.

Abstract

A testing platform tests an electrical and mechanical system such as an HVAC unit according to an algorithm that reduces the total testing time of the components of the system, while ensuring the safety of the system during system-wide testing. The platform uses constraints that are checked both before and during the testing to ensure that HVAC operating conditions are acceptable for starting and maintaining component tests. Preferably, the platform uses finite-state machines for each device to organize the component tests, allowing for monitoring of constraints and starting, pausing, and stopping component tests. Preferably, total test execution time is reduced by running component tests in parallel, running component tests based on loads of the components, or combinations of both.
