The continuous rise of the maximum load of air conditioners in the extremely high temperature weather of summer has brought a significant challenge on the power supply. The development of cooling system with photovoltaic and ice storage can play an important role. In this paper, a research on the optimal capacity configuration of the cooling system with photovoltaic and ice storage is carried out. Aiming at the lowest cost per unit of cooling capacity, the time-of-use electricity price, ice storage capacity and the maximum cooling load are considered to formulate an operation strategy. Under a given typical daily cooling load curve and photovoltaic output curve of a certain building, the influence of photovoltaic capacity and ice storage capacity on the cost of unit cooling capacity is analyzed. The case study shows that the optimal photovoltaic capacity is generally not affected by the cooling and ice storage tank capacity, and there is also an optimal value for the ice storage tank capacity.

The energy consumption statistics of buildings shows that cooling takes up a considerable portion of the energy demand. The peak-valley characteristics of cooling demand coincides with that of the electrical load in the microgrid. Thus the management of the cooling demand side can regulate the peak-valley demand and stabilize power fluctuations. This paper proposes a new energy management strategy that reduces the investment and loss of the battery energy storage system (BESS) by applying ice storage air-conditioning (ISAC) to the microgrid. Based on the load characteristics and BESS investment, the capacities of the chillers and the ice tank are analyzed. Penalty functions of ISAC and BESS are designed, according to which the stabilization command is dispatched. Finally, an actual case is analyzed by the proposed strategy, and the results verify the feasibility and effectiveness of the energy management strategy.

SUMMARYTurbine inlet cooling (TIC) is a common technology used to increase combustion turbine power output and efficiency. The use of mechanical or absorption chillers for TIC allows for more air cooling than evaporative methods and also imposes a significant parasitic load to the turbine. Thermal energy storage (TES) can be used to shift this load to off-peak hours. Use of thermal storage increases the flexibility of turbine power output, which benefits from the application of optimization tools. This paper explores the effect of combining TIC with TES to enhance the performance of a district cooling system that includes a gas turbine for power generation. The work illustrates how the system's performance can be enhanced using optimization. Application of multi-period optimization to the system that includes TES brings significant operational cost savings when compared with a system without thermal storage. It is also shown how TES provides demand-side energy management in the district cooling loop and supply-side management through the use of TIC. In addition to the optimization study, a thorough literature review is included that describes the current body of work on combining TIC with TES.
