During a transient state, the converter frequency ω VSG is delayed in following the grid frequency change, thereby transiently leading to a larger phase difference δ between the converter voltage and grid voltage and, thus the output power, P, surges to provide an emulated inertia response. In steady state, the converter frequency is equal to the grid frequency and,

2. One-way power flow: Grid-connected systems typically have a one-way power flow, where electricity flows from the grid to the system for consumption. These systems do not typically have the capability to export excess energy back to the grid. 3. No energy storage: Grid-connected systems typically do not include energy storage systems.
A grid-connected energy system is an independent decentralized power system that is connected to an electricity transmission and distribution system (referred to as the electricity grid). They are ideal for locations close to grid. The operational capacity is determined by the supply source.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
Typical On Grid Battery Energy Storage Applications: Voltage Synchronization: Grid-following PCSs continuously monitor the grid’s voltage waveform. They adjust the output voltage of the BESS to match the grid’s voltage, ensuring that the energy injected into the grid is at the correct voltage level.
So it takes care of seasonal load variations. As a result of which the overall efficiency of a grid-connected system will be better than the efficiency of a stand-alone system, as there is virtually no limit to the storage capacity, the generated electricity can always be stored, and the additional generated electricity need not be “thrown away”.
The connectivity to grid enables setting up relatively large-scale systems and hence they can operate at high plant load factors improving the economic viability of the operation. In a grid-connected power system the grid acts like a battery with an unlimited storage capacity. So it takes care of seasonal load variations.
