Two-Dimensional Systems and Mathematical Preliminaries
The order of the differential or difference equation is (N,M), representing the number of energy storage devices in the system. Often, N>= M, and the order is described using only N.

A Linear Time-Invariant (LTI) system follows most of the properties that a normal system follows, including memory and memory-less property, invertibility, causality, and stability. An LTI system is memoryless only if A. it does not store the previous value of the input B. it does not depend on any previous value of the input C.
As increasement of the clean energy capacity, lithium-ion battery energy storage systems (BESS) play a crucial role in addressing the volatility of renewable energy sources. However, the efficient operation of these systems relies on optimized system topology, effective power allocation strategies, and accurate state of charge (SOC) estimation.
There are two major reasons behind the use of the LTI systems − The mathematical analysis becomes easier. Many physical processes through not absolutely LTI systems can be approximated with the properties of linearity and time-invariance. The LTI systems are always considered with respect to the impulse response.
An LTI system is said to have memory when its output at any time depends on the previous value of the input. This does not mean its value does not depend on present values. It depends both on past and present values according to the situation.
