||As a result of increasing environmental and energy security concern, integration of clean sustainable energy technologies in the US is growing. Since some renewable energy sources are intermittent, a high penetration into the power grid could require the integration of energy storage technologies in order to meet the electricity demand. Furthermore the integration of large-scale electricity storage could help reducing transmission congestions, caused by transmission constraints and increasing electricity demand, and can provide economical benefit trough energy arbitrage.
The scope of this project is to estimate the value of large-scale electricity storage in the New England electric power system and to provide an insight in the challenges of implementing electricity storage.A simplified model of the transmission system (electricity flow and electricity prices) in New England is simulated in MatLab.
The aim is to simulate a business as usual scenario projected to 2020 and 2030 and assess where in the transmission system, at which scale and charge/discharge rate, electricity storage would be economically valuable. The forecasted parameters include electricity demand, installed capacity, electricity costs and transmission upgrades. Based on the outcome of the simulations the required features of the storage devices will be discussed with relation to today’s potential storage technologies.
As New England has a number of locations with strong winds suitable for commercial-scale wind power development particularly offshore, the discussion will open on the value of storage with increasing penetration of intermittent wind power generation.
