The smart active residential buildings play a vital role to realize intelligent energy systems by harnessing energy flexibility from loads and storage units. This is imperative to integrate higher proportions of variable renewable energy generation and implement economically attractive demand-side participation schemes. The purpose of this paper is to develop an energy management scheme for smart sustainable buildings and analyze its efficacy when subjected to variable generation, energy storage management, and flexible demand control. This work estimate the flexibility range that can be reached utilizing deferrable/controllable energy system units such as heat pump (HP) in combination with on-site renewable energy sources (RESs), namely photovoltaic (PV) panels and wind turbine (WT), and in-house thermal and electric energy storages, namely hot water storage tank (HWST) and electric battery as back up units. A detailed HP model in combination with the storage tank is developed that accounts for thermal comforts and requirements, and defrost mode. Data analytics is applied to generate demand and generation profiles, and a hybrid energy management and a HP control algorithm is developed in this work. This is to integrate all active components of a building within a single complex-set of energy management solution to be able to apply demand response (DR) signals, as well as to execute all necessary computation and evaluation. Different capacity scenarios of the HWST and battery are used to prioritize the maximum use of renewable energy and consumer comfort preferences. A flexibility range of 22.3% is achieved for the scenario with the largest HWST considered without a battery, while 10.1% in the worst-case scenario with the smallest HWST considered and the largest battery. The results show that the active management and scheduling scheme developed to combine and prioritize thermal, electrical and storage units in buildings is essential to be studied to demonstrate the adequacy of sustainable energy buildings.

In this article, a green microgrid is suggested which utilizes renewable energy units such as wind, solar, hydro, and biomass in conjunction with energy storage systems like batteries and the pumped storage. Different test scenarios are investigated to optimally use the power generated from the combined usage of the renewable energy units and the storage units. To judge the performance, a comparative feasibility analysis of the proposed approach is carried out to demonstrate the potential findings based on the total net present cost, levelized cost of energy, operating cost, and initial capital cost. In addition, the proposed solution may be subject to various changes in systems configuration with regard to the wind speed, solar radiation, streamflow, and the electric load; therefore, sensitivity analysis is also presented. Moreover, Indian policy interventions are considered to demonstrate the effectiveness of the proposed approach for a reduction in the overall revenue of the system.

The paradigm shift of large power systems to renewable and decentralized generation raises the question of future transmission and flexibility requirements. In this work, the German power system is brought to focus through a power transmission grid model in a high spatial resolution considering the high voltage (110 kV) level. The fundamental questions of location, type, and size of future storage units are addressed through a linear optimal power flow using today’s power grid capacities and a generation portfolio allowing a 66% generation share of renewable energy. The results of the optimization indicate that for reaching a renewable energy generation share of 53% with this set-up, a few central storage units with a relatively low overall additional storage capacity of around 1.6 GW are required. By adding a constraint of achieving a renewable generation share of at least 66%, storage capacities increase to almost eight times the original capacity. A comparison with the German grid development plan, which provided the basis for the power generation data, showed that despite the non-consideration of transmission grid extension, moderate additional storage capacities lead to a feasible power system. However, the achievement of a comparable renewable generation share provokes a significant investment in additional storage capacities.

Thermal Energy Storage Systems

Nano particles (NPs) have superior properties and hence can be used for various applications. The cold storage is most widely used in the preservation of agricultural and horticultural products. The cold storage maybe operated by vapour compression or vapour absorption cooling system. The operating cost of this system can be reduced by using renewable energy systems and thermal energy storage systems. The NPs are used to increase the performance of renewable energy and thermal storage systems. In recent years, phase change materials are used to increase heat transfer rate in solar cold storage units. The NPs can be used to absorb the ethylene gas produced during storage of fruits, so that the shelf life, freshness, firmness, and texture of the fruits can be maintained for longer storage duration. The NPs coatings also increases the shelf life and freshness of the fruits. This chapter discusses NPs, types of NPs, basics of cold storage systems, use of NPs in solar integrated cold storage, and effect of NPs coatings on fruits stored in cold storage.

We present the design and evaluation of a capacitor-driven efficient renewable energy management and sharing system, called REMS system, that is designed to replace battery-based energy storage units. We first identify potential applications and requirements of the REMS system. Then we describe the design of REMS system which aims at minimizing the energy leaked away and providing accurate and fine-grained energy sharing between embedded devices. We extensively evaluate our system under different real-world settings. Results indicate that our charging and discharging control can effectively minimize the energy leaked away. Moreover, the energy sharing design can efficiently share renewable energy among multiple devices and significantly extend the lifetime of a system.
