Energy Storage and Consumption Management as Elements of the Green Port Concept

Abstract

A modern seaport, as a major infrastructure hub of the world economy, has a significant impact on the environment in the area of ​​its location. Today, within the framework of the green port concept, the integration of renewable energy sources into the seaport power supply systems is a relevant issue. The volatility of renewable energy sources and, as a result, unstable electricity production leads to the necessity of energy storage systems implementation. The state strategy for the development of Russian maritime infrastructure and current global trends in the development of seaports confirm the relevance of intelligent power supply system implementation on the basis of Russian seaports, which will reduce the negative impact of port operations on the environment. The paper analyzes the tariff conditions and the annual power consumption schedule of the Kaliningrad seaport. An approach has been developed to regulate the load schedule of a 4^th price category consumer through an energy storage system that transfers consumption from planned peak load hours. The approach is implemented in the form of a software for simulating the operation of an energy storage device as a part of seaport power supply system. As a result of applying the software to the port load schedule, an analytical dependence of the amount of possible savings on the capacity of the energy storage device was obtained. Based on this dependence, the criteria for the economic feasibility of the proposed approach were determined when calculating the configurations of the energy storage system as part of the energy storage system on the example of Kaliningrad seaport.
