目前波浪能转换的发展主要集中在波浪能资源最高的地区；使用大型设备产生数百千瓦的电力。然而，可以使用较小的波浪能装置从低功率波浪中发电。这些额定值较低的波浪能转换器可以形成阵列，为离网的偏远沿海或岛屿社区供电。本研究介绍了使用低功率永磁线性发电机 (PMLG) 的离网系统的波浪能阵列的波线建模。添加了直流链路上的海上储能装置，以保持电压恒定以及逆变器的电流控制器，以便为离网连接的住宅负载提供恒定的低谐波功率。在MATLAB/Simulink环境中产生的仿真结果表明，波浪能阵列可以通过利用海上存储保持系统稳定，独立于住宅侧发电。此外，还根据从波浪中捕获的功率对两种不同类型的使用 PMLG 的波浪能设备控制器进行了比较。
Current developments in wave energy conversion have focused on locations where the wave energy resource is the highest; using large devices to generate hundreds of kilowatts of power. However, it is possible to generate power from low power waves using smaller wave energy devices. These lower rated wave energy converters can form arrays to supply power to remote coastal or island communities which are off-grid. This study introduces wave-to-wire modelling of wave energy arrays for off-grid systems using low power permanent-magnet linear generators (PMLGs). Offshore energy storage at the DC link is added to keep the voltage constant along with a current controller for the inverter in order to supply constant low harmonic power to the residential load connected off-grid. Simulation results produced in MATLAB/Simulink environment show that the wave energy array can generate power independently from the residential side by keeping the system stable using offshore storage. In addition, two different types of controllers for wave energy devices that use PMLGs are compared based on the power captured from the waves.
