Load model identification in electric power systems: a linear least-squares approach

Load model identification in electric power systems: a linear least-squares approach

Load modeling is one of the most important aspects when it comes to the stability analysis of electric power systems. The way we model loads significantly impacts the results of the analyses. The so-called ZIP model considers the voltage dependency of loads and serves this purpose very well. ZIP stands for the three defined load…

An energy storage model to analyze the energy arbitrage potential in a day-ahead electricity market

An energy storage model to analyze the energy arbitrage potential in a day-ahead electricity market

In this post, I discuss an energy storage model to analyze the energy arbitrage potential in a day-ahead electricity market. Energy arbitraging takes advantage of the price variations in the market where energy is bought at low prices and sold at high prices, thereby producing a profit. However, the profit depends on several factors, such…

Photovoltaic (PV) and energy storage: a viable symbiosis or an overrated investment?

Photovoltaic (PV) and energy storage: a viable symbiosis or an overrated investment?

The quick answer is – it depends… Technical cost-benefit analysis of a PV system complemented with energy storage for increased electricity self-sufficiency. Questions In order to properly analyze the costs and benefits of complementing a PV system with a storage system to increase self-sufficiency, several questions need to be answered. In the following, these questions…
