“…In [4], Ramp Rate Control is proposed, which holds the PV power output within a stable boundary. In [11], the authors propose to use a 10kWh Lithium-Polymer battery with a solar array in a home with a heuristic control algorithm to decrease peak power usage and to store unused solar energy. They introduced different operation modes for the battery, which are determined depending on the solar power, required load power and current state of charge of the battery.…”

“…This paper addresses the power flow control problem of a system with an energy storage device and introduces an optimal solution, which also has low computational complexity. Previous publications either focus on the optimization problem and solve it through high complexity tools [5], [13], [14] or provide heuristics that are not optimal [4], [6], [11], [12]. In addition, a linear battery model is used in most cases, which 1 Energy Storage and Battery are used interchangeably throughout this article does not correctly estimate battery lifetime, especially under high currents.…”

The need for a smarter grid is emerging with the increase of peak demand and the integration of renewable resources. A great solution for peak shifting and renewable energy smoothing is through the usage of energy storage devices. This paper focuses on the energy storage power control problem in small to medium sized power distribution systems with loads, energy storage devices and renewable resources connected to the grid. To the best of our knowledge, solutions in this area either focus on the optimization problem with a convex optimization solver, that have high worst-case complexities or on sub-optimal heuristics. This paper provides a low-complexity solution, ECO-DAC, which is optimal in terms of minimizing a multi-tier cost function. We show on multiple case studies that it is possible to save up to 21% in costs for electricity drawn from the grid, compared to the no-battery case.

“…Some companies offer Time of Use programs, in which they charge with differentiated tariffs depending on defined time slots. For this reason, it is convenient to use the energy stored to increase the self-consumption [7] or feed the grid [8]. The key from the economic perspective, is to define which process is better under certain circumstances.…”

This paper focuses on the most common PV-storage architectures that are designed for residential applications and that incorporate storage devices like batteries, hydrogen systems, supercapacitors, and flywheels. The main motivations and a comparison of the advantages and disadvantages of the architectures are presented. Moreover, some common approaches to perform intelligent power management are introduced.

“…From presented examples and as written by Petrollese and Cocco [10] there are two main effective ways for increased PV self-consumption: the energy storage and the load management. In the literature [11][12][13][14][15][16][17][18][19][20] a large number of studies have been done using battery storage for increase self-consumption. In [21][22][23][24] management shifting of flexible electric loads in households have been analysed to optimise the utilisation of the PV production.…”

Temporal load resolution impact on PV/grid system energy flows

View full text Add to dashboard Cite

In this paper, an investigation of the electrical load temporal resolution on the PV/Grid energy system flows, and self-consumption is done in order to determine the optimum parameters for modelling and simulation. The analysed PV/Grid power systems include a photovoltaic system with the nominal power of Pmax@STC=1.5, 2.5, 3.5 kW without storage unit connected to the grid. The results show that the temporal load resolution may have a high impact on energy flows as well as can be a critical issue for the system analysis accuracy even for the single household. It has been found that the load temporal resolution for energy consumption of 1-min yields reliable results, while data resolutions of 5 and 15 min are still sufficient, however, in that case, the daily electrical energy flows and in consequence energy self-consumption estimation error for selected days may exceed 15%. Acquisition time step longer than 15-minutes may increase error above 20% and from the designer’s point of view should not be used. The high and low temporal resolution experimental data of the electricity consumption (load) for a household are available in digital form on the author’s website http://home.agh.edu.pl/jaszczur.
