In wind power transmission via modular multilevel converter based high voltage direct current (MMC-HVDC) systems, under traditional control strategies, MMC-HVDC cannot provide inertia support to the receiving-end grid (REG) during disturbances. Moreover, due to the frequency decoupling between the. .
The energy storage unit is connected to the sub-module of the modular multilevel converter through the DC/DC link, which can effectively reduce the voltage-level requirements of the energy storage unit, and the energy storage capacity can be flexibly configured by changing the number of energy. .
In order to deal with the stability and security problems of power system operation brought by large-scale new energy grid connection, this paper proposes a modular multilevel energy storage power conversion system (MMC-ESS) with grid support capability. It utilizes the modular structure of the.

Any must match electricity production to consumption, both of which vary significantly over time. Energy derived from and varies with the weather on time scales ranging from less than a second to weeks or longer. is less flexible than , meaning it cannot easily match the variations in demand. Thus, without storage presents special challenges to .

Electricity can be stored directly for a short time in capacitors, somewhat longer electrochemically in , and much longer chemically (e.g. hydrogen), mechanically (e.g. pumped hydropower) or as heat. The first pumped hydroelectricity was constructed at the end of the 19th century around in Italy, Austria, and Switzerland. The technique rapidly expanded during the 196.

Grid-tie inverters convert DC electrical power into AC power suitable for injecting into the electric utility company grid. The grid tie inverter (GTI) must match the phase of the grid and maintain the output voltage slightly higher than the grid voltage at any instant. A high-quality modern grid-tie inverter has a fixed unity , which means its output voltage and current are perfectly lined up, and its phase angle is within 1° of the AC power grid. The inverter has an internal com.
